Schematic Details:

• schematic to add: ng add @td-vantage/ui-platform
• when run on an angular project, first covalent schematic would be run:
  ng add @covalent/core
  this will add core and other optional packages based on user input and theme.scss would be created based on what optional packages (makdown, highlight, etc.) user has selected.
• td-vantage/ui-platform would be added as a dependency in package.json
• theme.scss from ui-platform would not be copied as theme.scss would be added as part of covalent ng add
