Renamed the user function n_state_model.set_type() to align_tensor.reduction().

Added numpy int and float data types to the list of tested user function args.

Aliased self.func_iso_cone_elements to self.func.

A few fixes for the Frame_order class.

Added the Frame Order target function class.

It currently contains only one target function for an isotropic cone model directly optimised to the
Frame Order matrix elements.

Renamed the frame_order package to frame_order_matrix_ops.

This is to make way for the target function code.

Added functions for populating the Frame Order matrices for isotropic cones.

Added a missing import.

Shifted the print_frame_order_2nd_degree() function to generic_fns.

Added a function for printing out the 2nd degree Frame Order matrix.
