public byte[] getInstructionBytes() {
		return instructionBytes;
	}
Actual array of bytecode. 
The format of code in an insns array is specified by the companion document Dalvik bytecode. 
Note that though this is defined as an array of ushort, 
there are some internal structures that prefer four-byte alignment. 
Also, if this happens to be in an endian-swapped file, then the swapping is 
only done on individual ushorts and not on the larger internal structures.
@return array of bytecode
