//					<hash> to be any 32-bit unsigned int value.
// Parameters:		
//	const char* name		The string for which a hash will be generated
//	qboolean caseSensitive	If false, hash is generated from all lower-case
//	unsigned int maxHash	The non-inclusive maximum hash value desired
// 
// Returns:		unsigned int	32-bit unsigned hash value for <name>
