Another bug fix for the init() method.

Errors are not properly handled for all input data types.

Bug fix for the init() method.

Now errors are being placed in the pre-existing tensor, rather than a new tensor being added.

More fixes for error setting in the set() function.

Updated the init() and set() method to allow alignment tensor errors to be input.

Added the ability to perform Monte Carlo sims for the Frame Order theories.

For this, the following methods have been added:
__tensor_loop()
back_calc()
base_data_loop()
create_mc_data()
data_names()
model_loop()
return_error()
set_selected_sim()
sim_init_values()
sim_pack_data()
sim_return_param()
sim_return_selected()

Many other methods have also been modified.

Added a dummy eliminate() method.

Removed the sequence test in the Monte Carlo create_data() function.

No all data pipes in relax require sequence info.
