added routes for results screens and design essence for matrix mode
updates to results partials, started matrix display for design essence
refactored power service as instance factory, removed auto-caching
since this fails to trigger ng-model change events.  The cache
must be set by the calling controller.
several updates to stateController: added ajax call to calculate power,
added placeholders for matrix mode state functions
upload nearly working - still need to copy study design.  Also, not
updated mode.  Added style and cleaned up top screen.
