Profile

Add profile component.
This profile has been developed using d3js.
At the moment d3 is not compiled via the Makefile and the module is not included in the gaModules.

The example can be tested using this path "/src/components/profile/example/"

Profile has been tested on FF and Chrome, not yet on IE... (I am on my Ubuntu)
Translations are missing.

This widget is controlled using 2 events on the rootScope:
- gaProfileDataLoaded
- gaProfileDataUpdated

I thought that it was the best approach since we talked about developing a all in one measure component (e.g. distance, area, maybe angles and a profile button under).

Any suggestion related to user interaction and design are welcome as well.
