The number of integration points is now set as a cdp variable.

This is to allow the test-suite to cut the number of points down to a reasonable level.

The frame order rotor model numerical integration method has been changed.

The Monte Carlo numerical integration has been converted to the quasi-random method.

Saved a lot of memory with the Sobol sequence generation by using float16 and not keeping raw points.

The frame order create_sobol_data() method has been redesigned to handle all model types.

Started to convert the frame order rotor model to quasi-random numerical integration.

Renamed the number of numerical integration points for the switch of numerical integration methods.

This generalisation is to switch from Monte Carlo integration to quasi-random methods.

Created the rest of the frame order system test scripts.

Converted all of the CaM system test scripts to use the common base_script module for calculations.

Spun out all of the analysis code from the rigid frame order system test script into a base script.

This base_script module can be used for all of the CaM frame order system tests, as well as the
scripts in the data directories, to simplify the code base.

Spelling fixes.
