v2.0

This release contains breaking changes. Most notably:

• The CSS classes have changed to include an fsc-c namespace (including fsc-c-circles, fsc-c-draggable, fsc-c-circle-container);
• FSC-C now observes an event pattern to propagate the data. This simplifies the usage of FSC-C, but it does require end users to implement an event handler:

$( ".fsc-c-draggable" ).on( "fsc-c:data", function(event, data) {
  // process the data
  console.log(data);  
})
