/**
* Combines two jquery UI datepickers to provide a date range picker (that picks inclusive
* ranges).
*
* Properties:
* - startDate: The start of the date range. Should be a string in the YYYY-MM-DD format.
* - endDate: The end of the date range. Should be a string in the YYYY-MM-DD format. Note:
* date ranges are inclusive.
* - rangeChange: Called when one or both dates bounding the range change. If the dates are
* in an invalid state, the date will be null in this event.
* - submit: Called if the 'enter' key is pressed in either of the inputs.
*
* Usage:
* <piwik-date-range-picker>
