Updated layout to use the sample selector in the same view
Bring in a list of demos
Update demo list controller, and put the chart in the same controller as well
Removing usage of scope ID.

Rationale: If the div containing the `fc-chart` attribute has an ID, scope.id is set to that ID. FusionCharts cannot have the Chart Div ID and Chart ID as the same
Added all the Data XML files shipped with FusionCharts
Merge pull request #1 from skyronic/new-samples

Added samples, and minor updates to layout.
Moved xml data files under app/data/xml.
Created fcChartFactory service to deal with the FusionCharts API and provide simple way to build custom directives.
Remote data is now fetched by $http: can therefore use $http request/response interceptors.
Re-giggled the gh pages a little. Still needs much more love. Using a grouped select box fo the demo.
Now properly wrapping the lib in a closure.
