Merge pull request #2 from buildcom/master

Getting synced up with the repo for a push
Adds many features

adds vertical, style, custom initial values, and comments
corrects the location of a stray variable

$sce is an angular service not a variable, Strict Contextual Escaping. I
don't think I can rename angular service components.
Adds $compile so we can bind ng directives to our templates

We also removed the need for the $sce service and we now do not pass
strings from the controller and the directive. We also did some general
clean up so the code looks nicer
Adds the ability to add different colors to widget.

You can pass the hexadecimal color format to specify the colors of each
part.
