Completely remove pointless methods. Didn't notice any warnings when I commented them out earlier anyway. Re #1944

Try to get system tests passing. This includes temporary renaming of a method on Instrument. Re #1944.

Add a copy constructor to Instrument. Oh, and go on a const-correctness hunt that led this commit to touch slightly more than just the one class. Re #1944.

Refs #3638: Filled in CoordTransformAligned; it runs 2.5-3x faster than the more general affine transform.

Refs #3638: Added a class CoordTransformAffine so as to make CoordTransform base class a bare abstract class.

Refs #3638: Added a stub for CoordTransformAligned. Reverted CoordTransform to use the bare data types instead of the wrapped parameter types, resulting in a 30% speed up.

refs #3577 #3578 #3579 #3580

Refs #3635: Reworked helper into a GPUAlgorithm base class. Static members allow compiling kernels only once.

Refs #3635: Added some helper functions; a tester algorithm that simply tests if everything is working; a line in the .properties file to specify where the opencl kernle (.cl) files are located for loading.

refs #3580

Refs #262: Moved the new validators to a separate class that better reflects what they do. New method on algorithms setPropertySettings() to give an IPropertySettings to a given property. This allows you to make properties be hidden/disabled based on other properties.

Minor code reformatting.
