Would love to see a click/drag create capability in the day views

[GoogleCodeExporter]

Description of the new feature:
gwt-cal currently supports clicking at a time and creating an event at that 
time.  That's a GREAT feature.  I'd like to see this extended to where you can 
click and drag thereby creating an event at the click time of a duration to 
where the click was released.  Example:  Click at 9:00am, with mouse still 
down, drag to 1:00pm and release the mouse.  This would create an event from 
9:00am to 1:00pm.

Use Case:
Improved usability.
