/* This library is designed to give you three pieces of information:

	a. info.device -- the name/ID of the specific device: e.g. "Motorola Droid"
	b. info.os -- the name/ID of the operating system, e.g. "Android"
	c. info.category -- what class of device this is (mobile, tablet, desktop, appliance, etc.)
	
*/

/* version 0.9
   4/16/2010 - ABE
   added winOSFamily to desktopDeviceCategory
   changed categories sequence to detect desktops first -- and will set deviceCategory=unknownDeviceCategory.id if no match can be found.
