* Functions that are to be moved to //shared/htrutils captured in separate file. * Move files into new //shared/htutils package hash_function.go renamed to hashers.go * Refactor to reference moved methods in new package - Added import for htrutils to state and stateutil packages - Update references to imported funcs (append "htrutils.") - Updated funcs in htrutils to be exported where necessary * Add tests
