/**
* DatePicker 1.0.0
*
* A jQuery-based DatePicker that provides an easy way of creating both single
* and multi-viewed calendars capable of accepting single, range, and multiple
* selected dates. Easily styled with two example styles provided: an attractive
* 'dark' style, and a Google Analytics-like 'clean' style.
*
* View project page for Examples and Documentation:
* http://foxrunsoftware.github.com/DatePicker/
