  Added files:                 
    /r2/binarycloud/base/mgr	CacheManager.php 
  Log:
  This is the CacheManager, which contains code moved out from page (and some new stuff) for managing 
  caches of page output, module group output, and module output. This is not for generalized caching, 
  for that you can use the pear cache class.
