Improve usability for primary end-to-end use cases

Basic modeling operations for Teiid Designer can confusing because of the wealth of options and lack of UI assistance.

1) Create Cheat Sheets for multi-step modeling processes
2) Create Advisor framework to assist user in monitoring progress through these steps
3) Create new customizable top-down view of workspace showing model dependencies and project/folder containment.

• Allow drill-down editing ( EXAMPLE: Workspace > Project > Folder > Model > Table > Column )
