Create a description and mockup for merge component statement UI

Stories

This ticket is to create a mockup of a user interface for the functionality associated with the user story: As a user, I want to be able to merge/copy control implementation statements from component A into component B so that I can merge two different components together.

An initial method for the merger has been created in PR #220.

Discussion

• It would be nice at times to combine two components by taking the dozens of implementation statements from one component and adding those statements to another component. This solves the issue when somebody decides two components should be one component.
• A method Element.merge_component_statements has been created to support the adding control implementation statements from another element. This is currently a batch add filter that merges (copies) in all of the control implementation statements from the other component. There is a simple merge strategy. See: PR Add Element method to merge in control implementations statements from another component #220.

Acceptance Criteria

• One or more mockups
• Description
