Make SANS reduction python scripts more pythonic

[Mathieu Doucet]

In order to make the SANS reduction code more facility- and instrument-independent, we will need to refactor the current python code to make it more modular. A good way to start would be to refactor the current code to be more pythonic.

[Mathieu Doucet]

(In [5343]) Attempt to make the SANS reduction code more pythonic. The results of the execution of example_reduction.py was checked to be the same before and after refactoring. Test to come. Re #1421.

[Mathieu Doucet]

(In [5344]) Forgot one line to ensure backward compatibility. Re #1421

[Mathieu Doucet]

(In [5345]) Fixed another problem. Re #1421

[Mathieu Doucet]

(In [5346]) Minor change to accommodate python reduction script refactor. Re #1421

[Mathieu Doucet]

(In [5371]) More SANSReduction refactoring + added python unit tests to help refactoring effort. Re #1421.

[Mathieu Doucet]

(In [5385]) Access data directly. Re #1421.

[Mathieu Doucet]

(In [5413]) PythonAPI/scripts: First attempt to write a prototype for a general reducer in python, along with actual reduction steps for SANS. Re #1421.

[Mathieu Doucet]

(In [5414]) PythonAPI/scripts: Added documentation. Re #1421.

[Mathieu Doucet]

(In [5437]) Extended SANSReducer command set. Re #1421.

[Mathieu Doucet]

(In [5497]) Moved HFIR SANS definition to SANSInsts, using XML instrument parameters. Re #1421.

[Mathieu Doucet]

(In [5503]) Added reduction steps and options. Re #1421.

[Mathieu Doucet]

(In [5505]) Fixed dumb error... Re #1421.

[Mathieu Doucet]

(In [5507]) Moved all reduction tests to unit tests using the new design. HFIRSANSReduction now only kept for reference while we complete the work. Re #1421.

[Mathieu Doucet]

(In [5508]) Added background subtraction. Re #1421.

[Martyn Gigg]

(In [5529]) Fix file extensions in facilities test. Re #1398 Fix parameter map size test due to new BioSANS parameter file. Re #1421

[Steve Williams]

(In [5531]) Changes to the SANS unit tests to make them easier to run on my computer re #1421

[Mathieu Doucet]

(In [5554]) Add option to using a different loading step to accommodate other instruments Re #1421

[Mathieu Doucet]

(In [5575]) Move the detector to its Z position as part of the load to streamline the reduction steps. Re #1421.

[Mathieu Doucet]

(In [5585]) Fixed tests that failed because of latest changes to LoadSpice2D. Re #1421.

[Steve Williams]

(In [5595]) Added some code to Normalize to make it compatible with ISIS and added some ISIS compatibility comments re #1421

[Mathieu Doucet]

(In [5597]) Made a few changes to make code more compatible between ISIS and HFIR. Re #1421.

[Mathieu Doucet]

(In [5599]) Start to move HFIR-specific code into separate modules. Re #1421.

[Mathieu Doucet]

(In [5708]) Added functionality to deal with background transmission separately. Re #1421

[Mathieu Doucet]

(In [5833]) Minor clean up. Re #1421

[Mathieu Doucet]

(In [5868]) Correct minor bug from last commit. Re #1421

[Mathieu Doucet]

I'm closing this ticket since its main requirement has been addressed. We now have a working SANS reduction framework in python. All future modifications will have their own specific ticket.

[Martyn Gigg]

Confirmed that the new modules exist. They are used in the GUIs and they are indeed far a better than the original framework!
