* add placeholder for apply function * added apply function * add test coverage for apply utility * stylsitic name change in apply source code * stylistic format change to test * improved description of function parameters * moved the apply function to the public matrix functions * update location and reference of unit test * fixed function reference paths in apply for location in function * changed path to apply in apply.test * make apply a typed function, update unit test * added typing error test to coverage * remove apply.test.js from the utils test function * added transform function for apply * add unit test for apply.transform.js
