New Features

Added IgxTree component

Allows users to render hierarchical data in an easy-to-navigate way. The control is not data bound and takes a declarative approach, giving users more control over what is being rendered.
Features API for handling selection (bi-state and cascading), node activation, node expansion state.
Features extensive and easy-to-use keyboard navigation, fully compliant with W3 standards.
Code example for a tree contructured from a hierarchical data set:

    <igx-tree>
        <igx-tree-node *ngFor="let node of data" [data]="node" [expanded]="isNodeExpanded(node)" [selected]="isNodeSelected(node)">
            {{ node.text }}
            <img [src]="node.image" alt="node.imageAlt" />
            <igx-tree-node *ngFor="let child of node.children" [data]="child" [expanded]="isNodeExpanded(child)" [selected]="isNodeSelected(child)">
                {{ child.text }}
                <igx-tree-node *ngFor="let leafChild of child.children" [data]="leafChild" [expanded]="isNodeExpanded(leafChild)" [selected]="isNodeSelected(leafChild)">
                    <a igxTreeNodeLink href="{{leafChild.location}}" target="_blank">{{ leafChild.text }}</a>
                </igx-tree-node>
            </igx-tree-node>
        </igx-tree-node>
    </igx-tree>

For more information, check out the README, specification and official documentation

IgxHierarchicalGrid
- Added support for exporting hierarchical data.
IgxForOf, IgxGrid, IgxTreeGrid, IgxHierarchicalGrid
- Behavioral Change - Virtual containers now scroll smoothly when using the mouse wheel(s) to scroll them horizontally or vertically. This behavior more closely resembles the scrolling behavior of non-virtualized containers in most modern browsers.

IgxGrid, IgxTreeGrid, IgxHierarchicalGrid

The IgxRowAddTextDirective allows to customize the text of the row adding overlay.

     <igx-grid [rowEditable]="true">
        <ng-template igxRowAddText>
            Adding Row
        </ng-template>
    </igx-grid>

A new summaryFormatter input property is exposed by the IgxColumnComponent, which is used to format the displayed summary values for the columns.

    public dateSummaryFormat(summary: IgxSummaryResult, summaryOperand: IgxSummaryOperand): string {
        const result = summary.summaryResult;
        if(summaryOperand instanceof IgxDateSummaryOperand && summary.key !== 'count'
            && result !== null && result !== undefined) {
            const pipe = new DatePipe('en-US');
            return pipe.transform(result,'MMM YYYY');
        }
        return result;
    }

    <igx-column field="OrderDate" header="Order Date" [sortable]="true" [disableHiding]="true" [dataType]="'date'" [hasSummary]="true"
        [summaryFormatter]="dateSummaryFormat">
    </igx-column>

Two new column types are introduced dateTime and time. In order to operate with them is necessary to set the column property dataType to 'dateTime' or 'time'.

<igx-column field="OrderDate" header="Order Date"  [dataType]="'dateTime'" >
</igx-column>
<igx-column field="ClosingTime" header="Closing time"  [dataType]="'time'" >
</igx-column>

Behavioral Change - Column Autosize feature now does not handle templated headers where the first level children are sized based on parent like default div and etc. Autosizing for such headers will not result in change.
Behavioral Change - Calling autosize through the IgxColumnComponent API now takes into consideration the minWidth and maxWidth of the column.
A new IgxColumnComponent input property is exposed called autosizeHeader, which if false, allows the autosizing to ignore the header cell and autosize only based on content cells.

IgxTabs
- The tabAlignment property of the IgxTabs component replaces the type property and enables you to set the tab alignment to start, center, end and justify.
- The igx-tab-header supports igx-prefix and igx-suffix directives in its ng-content.
IgxBottomNav
- The IgxBottomNav component exposes disableAnimations property which determines whether the contents should animate when switching the selected item. The property is set to true by default which means that the animations are disabled.
IgxOverlayService
- detach and detachAll methods are added to IgxOverlayService. Calling detach will remove all the elements generated for the related overlay, as well as clean up all related resources. Calling detachAll will remove all elements generated by any call to IgxOverlay attach, and will clean up all related resources. Note: calling hide or hideAll will not clean generated by the service elements and will not clean up related resources.

IgxCombo

Any changes to IComboItemAdditionEvent.addedItem will be reflected in the item added to the data.
IgxComboComponent.onAddition is now cancelable. You can prevent the item from being added by setting the event args cancel property to true.

public handleComboItemAddition(event: IComboItemAdditionEvent): void {
    if (event.addedItem[this.combo.valueKey] === 'ForbiddenValue') {
        event.cancel = true;
    } else if (event.addedItem[this.combo.valueKey] === 'Change Me') {
        const index = this.iter++;
        event.addedItem = {
            [this.combo.valueKey]: `customId${index}`,
            [this.combo.displayKey]: `New item ${index}`;
        }
    }
}

IgxDateTimeEditor
- value accepts ISO 8601 string format.
- spinDelta input property which allows a user to provide different delta values that will be used for spinning. All parts default to 1.
- increment and decrement methods now accept an optional delta parameter which targets the currently spun date portion. It takes precedence over the values set in spinDelta.

IgxDatePicker

value accepts ISO 8601 string format.

The actions template now exposes the Calendar component as implicit context:

<igx-date-picker>
  <ng-template igxPickerActions let-calendar>
      <button igxButton="flat" (click)="calendar.viewDate = today">Today</button>
  </ng-template>
</igx-date-picker>

IgxTimePicker

value accepts ISO 8601 string format.

The igxPickerActions directive can now be used to provide custom buttons to the picker's pop-up:

<igx-time-picker #timePicker>
  <ng-template igxPickerActions>
      <button igxButton="flat" (click)="timePicker.close()">Close</button>
  </ng-template>
</igx-time-picker>

IgxDateRangePicker

value start and end accept ISO 8601 string format.

The igxPickerActions directive can now be used to template the pickers Done button:

<igx-date-range-picker #rangePicker>
  <ng-template igxPickerActions>
      <button igxButton="flat" (click)="rangePicker.close()">Close</button>
  </ng-template>
</igx-date-range-picker>

Themes:

Breaking Changes:
- IgxButton theme has been simplified. The number of theme params (igx-button-theme) has been reduced significantly and no longer includes prefixed parameters (flat-*, raised-*, etc.). See the migration guide to update existing button themes. Updates performed with ng update will migrate existing button themes but some additional tweaking may be required to account for the abscense of prefixed params.
- The igx-typography mixin is no longer implicitly included with igx-core. To use our typography styles users have to include the mixin explicitly:
```
@include igx-core();
/// Example with Indigo Design theme:
@include igx-typography($font-family: $indigo-typeface, $type-scale: $indigo-type-scale);
```
