Add index.html for testing module and config.rb for Compass

Added an index file that we can serve to test that the component
appears as expected. Added a config.rb for Compass to monitor and
compile sass to css.
Add module directive, service and partials. Add some boxes to index.

Add the ported version of the scorecardModule directive and the partials
for the different types, as well as the scorecardService (previously
called departmentService). Get the other services with npm install and
include one of each type of scorecard in index.html
Add module specific styles and include styles package as devDependency

Add scorecard specific styles and export these. Include styles package
as devDependency to compile with variables and to test that modules
appear as they should.
Use scorecardService from Services package

Use the scorecardService from the Services package rather than the
local temporary one. Update index.html to use an existing ID for the
test boxes.
Add filters to get trend icons for indicators

Require the filters package and use the numToTrend and termToIcon filters
to get icons representing the trend for category indicators.
Add trend icons to summary type scorecard
Test scorecard module

Create tests for the scorecard module and update Makefile to run Karma
correctly on 'make test'.
