COMP: Attempt to fix warning about \param.

There seems to be conflict between the syntax of \brief and the use
of \param.  It is still not clear why. It happens only in this file.

ENH: Refactor KWStyle testing

All ITK Modules C++ source and test files will now be checked with KWStyle,
except External, Remote, and ThirdParty. A separate test for Review code
is no longer needed, and is removed.

Support for GCC-format output of KWStyle is added.

The list of KWStyle error exceptions (ITKOverwrite.txt) is greatly
reduced in length.

A bug preventing the KWStyle Make target from running is fixed.

Finding the KWStyle program is factored out into an independent CMake
module.

Several unnecessary files are removed, including a C shell script
that wasn't portable and only checked individual directories.
