Debug class improvements.
Debug valgrind output.
Fix MSVC compiler warnings.
Temp fix to make QGenRecon work correctly.
Fix bug in file read-in.
Add new string-manipulation functions.
Coordinate with commit 7e5ae0bcf14df18fb6d8751fd9c8cabbc1273eca in research repository.

Improve file organization.

1. Move "DetermNumElements" into StringManip namespace and remove XRParamIO namespace.

2. Move included *.pri files to their local project directories.  Intent is to update these files when adding/removing files from the projects and then have those changes automatically included in any projects which include the *.pri files.
Move non-templated functions to separate *.cpp file.

Templated functions still defined in StringManip header.
Implement transposing of arrays.

Compiles.  Not tested.
Testing array transposition.

Not working yet.
Fix transposition of 2D array.
Fix implementation of array transposition.

Works for 3D arrays when all dimensions are equal.  Only the (0 <--> 1)
transposition works for general arrays.

If size1 == size3 (nrows == nslices), transposition also works.
More updates/testing of transposition.
Fix implementation of array-transposition.

FFTW code contained within #ifdef statements to allow compilation without requiring FFTW.

Only the innermost dimensions may be transposed using FFTW.  Higher-dimensions only support use of a copy array.
Update documentation for proper compilation of array classes.

No functional change.

Updated the *.pri file to add the source directory to the include path.  This means that the *.pri file only needs to be included by a *.pro file in order to use the code within that project.
Add dummy code to suppress 'unused variable' code.
Fix MSVC compiler errors/warnings.
Commit before merge.
Merge remote-tracking branch 'origin/master'

Update *.pro file for compilation on Mac OS X 10.6.

Compilation doesn't succeed yet due to missing FFTW dependency (among others).  This update is basically useful for controling Mac compilation separate from Unix compilation.
