This commit replaces all header guards in Kernel with #pragma once

Git only converts CRLF to LF and not CR so to produce
the same SHA as git we must do the same.

A new boolean parameter SimulateTracksForEachWavelength has been added to
the MonteCarloAbsorption algorithm. This exposes a switch on the MCAbsorptionStrategy
that was present before this change but was hardcoded to False.

The parameter NumberOfWavelengthPoints is only required if SimulateTracksForEachWavelength
is set to True. This change means that an attenuation factor is calculated for all wavelength
bins if SimulateTracksForEachWavelength=false. To facilitate this a performance enhancement
has been made to the Material class to calculate the total scatter cross section and the
absorption cross section once when the Material rather than every time these cross sections
are retrieved by the MonteCarloAbsorption calculation.

This change required some unit and system tests to be updated eg ILLDirectGeometryReductionTest
has been changed to remove the NumberOfWavelengthPoints parameter and the reference file to be
updated. To make this test more robust I have increased the number of scenarios used in the MC
simulation from 5000 to 20000

This commit adds tests to unit and PDFFourierTransform todo with the new atomic distance unit.

Newer boost bind seems to be causing
compiler warnings on Windows. It's no
longer required now bind is in the STL.

Updates the associated instrument to one from the facility when a
facility is changed. This could fix numerous spurrious failures where
unit tests will assume that a change in facility -> a change to an
instrument from said facility

Main change is to add an overload of registerFeatureUsage that accepts a
simple string in addition to the existing method that takes a vector of strings

Update some further calls to registerFeatureUsage that had appeared in master
Also change trimming behaviour so trimming of feature names is done on copy
rather than in place

Now accepts:
- an enum for feature type rather than a string eg Algorithm
- a vector of strings for the feature name instead of string (eg class1->method1)

Also updated pre-existing calls to registerFeatureUsage in C++ and Python

- Remove bind1st/bind2nd usage.
- Avoids an internal compiler error in gcc with getProperty.
- Adds wrapper around sip executable to process the output and
  remove the throw specifiers. They are not allowed in C++ 17.

It was unused and gave the impression that a wavelength
dependent calculation was being used.

Convert char to wchar instead to avoid possible data loss.

It is unused as users how gone in a different direction
with the project.
