This release provides more tests with BigQuaternion polynomial coefficients. It fixes a left-right bug in solvable polynomials monic() method. (left and right monic must be distinguished although the inverse of the leading base coefficient is a left and right inverse.) And fixes to leftMonic() where required. It adjusts the polynomial reverse() method with using conjugate() on coefficients. More tests for Ore conditions for polynomials with quaternion coefficients. Fixed default implementations in interface MonoidElem for left, right and two-sided operations by throwing exceptions when not correctly overridden.
