Arena class
An Allocator which frees all allocations at the same time.
The arena allows you to allocate heap memory, but ignores calls to free. Instead you call releaseAll to release all the allocations at the same time.
Also allows other resources to be associated with the arena, through the using method, to have a release function called for them when the arena is released.
An Allocator can be provided to do the actual allocation and freeing.
Defaults to using calloc
