-* Description: 
-* Cluster class used to allocate cluster numbers for directory entries 
-* and while writing file contents. And it is responsible to create the 
-* MAP of content starting cluster to ending cluster which can be used 
-* to generate FAT table. Since the cluster number is unique all over the
-* filesystem component, this class is designed as singleton class.
