Modifications of the test suite script for calculating synthetic CPMG data.

The imports in cpmg_synthetic.py are now all used, rather than being commented out. This allows the
find_unused_imports.py devel script to pass.

Changed the imports in the test_monte_carlo_mean.py script.

This inconsequential change is to avoid false positives from the find_unused_imports.py devel
script.

Fix for the find_unused_imports.py devel script - the #! line must be at the top.

A directory can now be supplied on the command line for the find_unused_imports.py devel script.

Added a copyright notice to the find_unused_imports.py development script.

This is mainly to indicate how out of date the script will be in the future.

Added an exception system to the find_unused_imports.py developer script.

Sometimes pylint will give an "Unused import" warning for imports that are needed by the module.
Therefore an exception list of the file name and module has been created to skip these warnings.
The list covers the dep_check module and all of the profiling_*.py scripts in the directory
test_suite/shared_data/dispersion/profiling/.

Unused import clean up in the test_suite/shared_data/curve_fitting/profiling directory.

The scripts in this directory have been cleaned up to remove unused imports.

Unused import clean up in the test_suite/shared_data/curve_fitting/numeric_topology directory.

All the scripts in this directory have been cleaned up to remove unused imports. In one case,
commented out code was replaced with an 'if 0:' statement to silence the unused import warnings from
the devel_scripts/find_unused_imports.py script.

Updated some unused frame order scripts to use the new minimise user function design.

Removal of unused imports from the test_suite/shared_data/frame_order/simulation scripts.
