Copied the units_conv.c from 15 that includes the new units to master.
Swept through the code removing includes to Unit.hh and UCF.h where they
are no longer needed. Remade makefile dependencies.
refs #231
Changed the include for udunits to #include <udunits2.h> to work
on all platforms. Added the include directory /usr/include/udunits2
for Linux.
refs #231
Initial checkin of using udunits for measurement units conversions. Replaced
our conversion code in ICG and swig code to use udunits.
Also added code to convert unit symbols that we used in Trick that are different
names in udunits.
Added a sim_object that will eventually allow users to specify a custom
set of files to read units information.
refs #231
For addition and subtraction, we created a new routine that
only scales second units to the first. We apply it to all
conversions when adding and subtracting, but it only changes
the temperature results, because that is the only units that
has a bias factor. The comparision conversion routines were not
changed.
refs #202
Reorganized. Created a new top level include directory that will hold all of Trick's header files. Moved all of the Trick headers to this directory. Created a libexec directory that holds all of the executables that users don't need to execute directly. Changed all of the executables remaining in bin to start with "trick-". In the sim_services directories changed all source files to find the Trick headers in their new location. Since all of the include files are gone in sim_services, removed the src directories as well, moving all of the source files up a level. Moved the makefiles, docs, man, and other architecture independent files into a top level share directory. Renamed lib_${TRICK_HOST_CPU} to lib64 or lib depending on the platform we're currently on.
