Create an array of binary digits (bits). By default, the array is empty and has a capacity of 0 bits. Optionally specify the initialLength (in bits) of the array. If initialLength is not specified, the default length is 0. If initialLength is specified, optionally specify the value for each bit in the initialLength. If value is not specified, the default value for each bit is false (0). Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used.
