Feature/customize

[TamarLahav]

The changes we made are:

1. Adding an option “highlightsLineCap” which can be one of the following: ‘round’, ‘square’ or ‘butt’. (default is ‘butt’)
   It sets the context.lineCap within the drawRadialHighLights function of the RadialGauge object.
2. Adding a format option to set the “units” attribute.
   For example “{value} % {title}” which replaces the attributes inside {} to the same member in the option object.
   So if title is set to “Hour” and value to “50” the units will be “50% Hour”.
