LoadInstrument algorithm now uses OptionalBool. MandatoryValidator used and tests for that class have been fixed.

I don't think this method is used anywhere, which is a good thing as it
was returning a pointer to a temporary.

It makes no sense for some property types (bool, string) and is
only used once.

MultiFileProperty changed to store a vector of vectors of file names. File
names that share a vector are to be added. Old functionality can be produced
by calling "flattenFileNames".  See source code for more info.

MultiFileProperty was used in one place previously (MDMergeFiles), this has
been modified to relect these changes.

Load now implemented in terms of MultiFileProperty, though its interface is
unchanged.  "Filename" input is now parsed as a multi file, and if that
fails old functionality is attempted.  Error reports will output the result
of both attempts.

Some additional template specialisations / "toString" overloads
surrounding the Property class heirachy were necessary to properly support
std::vector<std::vector<std::string> >.

Changed from an INTEL to a APPLE ifdef

Refs #3175. Move the macro for defining IPropertyManager::getValue functions to the header so that all user-defined types can access it. Also implement a test for MatrixProperties being passed to algorithms. We have one problem now with this kind of code: DblMatrix R = getProperty("R"). IPropertyManager can't define a template conversion operator because Visual Studio has a problem with the std::string version that even a specialization doesn't cure.

Modify the SolidAngle calculation for cylinders to EXCLUDE the end caps so that it closely approximates the effects of shadowing for stacked cylinders. Also cleaned up some indentation in renderinging code and made an error message clearer in IPropertyManager. Re #2596

Fix the mac build. The intel compiler defines size_t to unsigned long which doesn't match uint64_t that was exported. Re #3008

Refs #2751: Added stub for Fake MD data algorithm. Made properties report the type they expected when you give the wrong value.

Rename Framework code directory to just that. Also delete Main and VS & Eclipse project file. Re #1881.

re#1699 -FacilityInfo is changed to support multiple information catalogs .IPropertyManager is changed to support array property of type long long

ChangeFramework code changes for Visual Studio 2010 happiness. For the reasons why the introduction of nullptr was necessary, see http://connect.microsoft.com/VisualStudio/feedback/details/520043/error-converting-from-null-to-a-pointer-type-in-std-pair Re #1389.
