Add gridObjectTestUtils.

Before:

    var gridTestUtils = require('lib/gridTestUtils.spec.js');
    gridTestUtils.expectHeaderColumnCount('users-table', 6);
    gridTestUtils.expectHeaderCellValueMatch('users-table', 0, 'ID');
    gridTestUtils.expectHeaderCellValueMatch('users-table', 1, 'Name');
    gridTestUtils.expectHeaderCellValueMatch('users-table', 2, 'Email');

After:

    var GridObjectTest = require('lib/gridObjectTestUtils.spec.js');
    var usersGrid = new GridObjectTest('users-table');
    usersGrid.expectHeaderColumnCount(6);
    usersGrid.expectHeaderCellValueMatch(0, 'ID');
    usersGrid.expectHeaderCellValueMatch(1, 'Name');
    usersGrid.expectHeaderCellValueMatch(2, 'Email');
