The user functions without a base class are now supported in the prompt, script, and GUI modes.

This is for the auto-generated user functions not stored in a user function class object.

Fix for the Uf_info.add_uf() method - the re.search() call was matching '.' to all characters!

The 'num_or_num_list' and 'num_or_num_tuple' argument types are now supported in the GUI.

These are for the auto-generated GUI user functions. The 'num_or_num_tuple' argument type is used
for the diffusion_tensor.init user function, for example.

This was failing in many cases, especially where the value is not a tuple to start with.

Improvements for the diffusion_tensor.init user function data setup.

Whitespace fix.

Converted the palmer user functions to the auto-generation design.
