This test is catching a radix-k bug concerning no-split rounds.

The SimpleTiming test is now available when compiling without OpenGL.

Also converted the CompressionSize test to no longer depend on OpenGL.

The copyright on all source now has the current preferred legalize.  All
source now also states that the license is New BSD.

Changed the build system to include all of the strategies into the
IceTCore library.  The separation was mostly a coding convienience
on the library side.  It was rather silly for the user perspective
as you always used both libraries.  Also, this was becoming less
convienient as the core library really relies on things in the
stratgies library and you have to carefully pass pointers and
structures around.

This change is driven by some errors I am encountering that might
be caused by using uninitialized strategy objects.  My next step is
to just identify stratgies by enumerations.  This will get rid of
any such problems.

Also changed icet to IceTCore.

Previously, the OpenGL and MPI libraries were linked to everything
with a general LINK_LIBRARIES CMake command.  Now, only use
TARGET_LINK_LIBRARIES to bind libraries to a specific target.  Not
only is this cleaner, but it also helps verify that libraries that
should not depend on these libraries don't.

Created a new src directory (gl) for a new IceT library (icet_gl).
This library will encapsulate all the OpenGL dependent functionality.
As a first step, ICET_READ_BUFFER was moved to this library.

Previously the tests used some hack-ish code for creating windows
on X and Win32.  Unfortunately, this meant that I could not run
the tests on Mac, where I now do most of my development.  Rather
that make my own knock off again, I am using a well-established
portable library.

the ordered composition were also fixed.
