Reverted r23508-23507 as the correct is dimensions (None, 3) for x,y,x positions.

The command used was:
svn merge -r23508:23507 .

.....
Modified the dim dimensions to (None, 4) to allow the user to change number of points in the GUI.

THe first dimension was used as a counter, the last 3 dimensions is for x,y,z position.

This is for the user function dx.map.

Modified:
trunk/user_functions/dx.py

Bug fix for the Sequence_2D GUI element.

This is used for the user function windows in the GUI for setting lists of lists or matrices. The
GUI element GetValue() method will now return None if nothing is set. This prevents a list of lists
of None being added to the main user function window.

Expanded the User_functions.test_structure_rotate GUI test to catch more problems.

Now the rotation matrix value in the user function window is set to a series of invalid values to
test if the Sequence_2D GUI element will handle the rubbish input. This is to mimic user errors.

Expanded the User_functions.test_structure_rotate GUI test.

The rotation matrix argument checks for the Sequence_2D GUI element have been expanded to check that
setting nothing (blank element) returns nothing (None). The other checks have also been slightly
modified.

Simplified the User_functions GUI tests.

The exec_uf_pipe_create() method has been created to simplify the data pipe creation in the tests.

Partial fix for bug #22100.

This is the bug report at https://gna.org/bugs/?22100, the rotation argument for the
structure.rotate user function cannot be changed in the GUI, as an AttributeError is raised.

The append_row() method call has been replaced by the correct add_element() call.

Modified the dim dimensions to (None, 3) to allow the user to change number of points in the GUI.

This is for the user function dx.map.

Expanded the User_functions.test_structure_rotate GUI test.

This is to more extensively check the 'float_matrix' user function argument type in the GUI.

Some more fixes for the User_functions.test_structure_rotate GUI test.

The open_dialog() method cannot be used, as it deletes the window at the end. Instead the
selection_win_show() and selection_win_data() method combination is used.
