Example class HWCD

this is an example of a detection routine for "shiney plastic disc drives". it uses an internal table to check what drive has what capability, as a central discover database for this info does not exist (that i know of).

first, it checks to see if a cdrom driver is loaded, then checks what device its loaded for. the only results of this script should be a jhwdetect.var (for debugging), and one of four classes, depending on what the drive can do. the four classes are "HWCDROM HWDVDROM HWCDBURN HWDVDBURN"
