Detailed Description

Simple block allocator.

This is simple allocator for cases where we want to free all memory at once.

The allocator allocates memory in size pre-defined blocks and hands out memory from such pools until the block memory is exhausted. The allocator does not have to maintain free blocks, since all memory is freed at once, which makes the code super simple and fast.
