Fix for the frame_order_models.Frame_order setup within minimise().

Fixed for the __minimise_setup_tensors() method.

Modified the reduction() function to store alignment tensor indices rather than names.

Created the __minimise_setup_tensors() method to compile the data needed for optimisation.

Added a check for incorrectly supplied arguments.

Preliminary support for optimisation against alignment tensors.

Added the func_iso_cone() and __init_iso_cone() methods.

Missing numpy imports.

Fixed the arguments of compile_2nd_matrix_iso_cone().

Shifted more code into the compile_2nd_matrix_iso_cone() function.

Created the compile_2nd_matrix_iso_cone() function for building the 2nd degree Frame Order matrix.
