Added LSH_CORE_ARRAY structure for hashtables instead of linked lists. Maintained Backwards Compatibiliity with indexes build for linked list format. Added tests for indexing and merging. Tested backwards compatibility OK.\n\n The purpose of the LSH_CORE_ARRAY data structure is greater space efficiency and L1/2 cache usage. Essential for multiple indexes with multiple hashtables in RAM
