Allocator::Allocator	(	const char *	name,
		unsigned int	element_size,
		unsigned int	chunk_size = 128,
		unsigned int	alignment = 8
	)			[inline]

Creates a new allocator.

Parameters:

	name	identification tag used for mem tracking .
	element_size	size of memory blocks to be allocated.
	chunk_size	number of units to be allocated if free pool is empty.
	alignment	of objects must be a power of 2.
