Detailed Description

Creates bit allocator for blocks in the group simpler.

A group is a selection of blocks on the disk. Typically the number of blocks in a group is determined by the number of bits a block holds. This makes the bit allocator for blocks in the group simpler plus is allows a simple way to localise access to files and directories.
