//
// Description:
//	Create cache files on disk for the selected shape(s) according
//  to the specified flags described below.
//
// $version == 1:
//	$args[0] = time range mode:
//		time range mode = 0 : use $args[1] and $args[2] as start-end
//		time range mode = 1 : use render globals
//		time range mode = 2 : use timeline
//  $args[1] = start frame (if time range mode == 0)
//  $args[2] = end frame (if time range mode == 0)
//
// $version == 2:	
//  $args[3] = cache file distribution, either "OneFile" or "OneFilePerFrame"
//	$args[4] = 0/1, whether to refresh during caching
//	$args[5] = skip, use $cacheDirectory argument
//	$args[6] = 0/1, whether to create a cache per geometry
//	$args[7] = name of cache file. An empty string can be used to specify that an auto-generated name is acceptable.
//	$args[8] = 0/1, whether the specified cache name is to be used as a prefix
//	
// $version == 3:
//	$args[11] = simulation rate, the rate at which the cloth simulation is forced to run
//	$args[12] = sample mulitplier, the rate at which samples are written, as a multiple of simulation rate.
//
// $version == 4:
//	$args[13] = 0/1, whether modifications should be inherited from the cache about to be replaced. Valid
//				only when $action == "replace".
//	$args[14] = 0/1, whether to store doubles as floats
// $version == 5:
//	$args[15] = cache format,
