Angular Colorpicker

An angular colorpicker for use with angular views. Fashioned after [jQuery Minicolors] (https://github.com/claviska/jquery-miniColors/).
Looks like keys for _.pick() should be individual args. (not wrapped in an array)
http://underscorejs.org/#pick

Looks like it was changed recently.
