I've shortened ExperimentInfo::loadInstrumentInfoNexus a lot.

Before I convert this to a vector of workspaces, I notice that the same variable name WS is used both for local variables, and member variables. This is utterly stupid and bound to cause problems in the future, so i'm fixing the naming here first.

 1. Change the filename reported for nexus files if xml contained within
 1. Stop saving the filename to nexus processed files
 1. removed some unused includes

Still to do:
 1. cache SHA1 checksum if needed
 1. Manually test
 1. update documentation
 1. investigate this error:

ctest -C Debug -J 4 -R LoadEventNexusTest -V

re #11818

 1. IDS mangling used for checksum is now inst name + sha1 of xml
 1.1. sha1 is computed after converitng to linux line endings and trim
 1. VTP file names changes to be same filename as IDS mangling
 1. VTP save directory moved to appdata/mantidproject/instrument/geometryCache
 1. VTP file saving simplified as files based on a checksum cannot be out of date
 1. unit tests updated to account for this
 1. unused methods removed from IDFObject
 1. InstrumentDefinitionParser changed to initialise during constructor
 1. XML parsing changed to lazy load rather than during initialisation.

Still to do:
 1. cache SHA1 checksum if needed
 1. Change the filename reported for nexus files
 1. Manually test
 1. Stop saving the filename to nexus files
 1. update documentation

Switched file to HRPD file to improve speed.

swap contents of new map with contents of old map instead.

Refs #9059

The multimap was continuously growing as there was no way of checking
if a given parameter for a component was already loaded. The storage
is now a map with key <Component*,name> so that only unique
component/named pairs will be stored.
Refs #7743.

This now returns a human-readable string detailing the structure
of the workspace.
Refs #7708

This way we can use a more general mutex rather than the specific
critical section used in cow_ptr. Also move some calls that access
the object directly to use the accessor methods that should prevent
access to the object while it is being copied.
Refs #7677

exposes ExperimentInfo::getInstrumentFilename() to Python.

Removed the method that only took the instrument name in favour
of a default parameter for the date.

Includes basis for creating a simulation workspace, the fitting function itself and the TobyFit
resolution model.

Allows a single name to be used when different run logs are required for
different instruments, e.g. different temperature log names.

Also removed the extra_data group and refactored code.

Allow user to get instrument definition file without specifying
a date, in this case the current date will be used.
