boolean K_BHeapFree(bheap_t *const heap)
Free the binary heap.
This does NOT free the data held within the binary heap items. Make sure those can still be freed manually.
Input Arguments:-
heap - The heap to free
Return:-
True if the heap was freed successfully, false if the heap wasn't valid to free
