Christopher Kelly 1b84f59273 Added a mixed precision multishift algorithm for which the matrix multiplies are performed in single precision but the search directions are accumulated in double precision. ...

A reliable update step is performed at a tunable frequency to correct the residual. A final mixed-prec single-shift solve is performed on each pole to perform cleanup if necessary.
A test is provided to demonstrate the algorithm.
