increase unsafeGet usage
implement elementMin and elementMax
elementMin and elementMax for ADiagonalMatrix
optimised elementMin and elementMax for double arrays
more optimised element ops
more elementMin and elementMax overrides
more min/max overrides
more min and max overrides
use unsafe get for elementMin
more element operation overrides
JoinedArray min and max
clever elementMax for boolean vectors / matrices
element ops for Matrix22
more min/max overrides
enhance repeated value vectors
better sum, min ,max for dense array matrices
add ARectangularMatrix base class
make AArrayMatrix extend from ARectangularMatrix
better BroadCastVectorMatrix extending from ARectangularMatrix
more rectangular matrix overloads, make shape final
