yPlot Code

For some reason the order of -i options must now be reversed. However,
I am happy to make that change because this seems to be a more logical order.
The result of this change is "make install" works again (but with some
compiler warnings I will attempt to address next).

Tag for version 1.2.0

Completely regenerate (previous versions done with cvs2cl) ChangeLog using

svn log --verbose .

Serialize yplot.so and 70yplot.i creation so the latter does not interfere
with the former for parallel builds.

Set up cpack to create source tarballs using "make package_source".

Many spelling tweaks resulting from ispell.

Some reorganization and many other tweaks resulting from a critical
read-through.

Remove Id data since this shows up in the ytut.ps.gz result.

Use EXAMPLES_DIR and DOC_DIR variables (and the existing Y_SITE variable)
to specify all install locations.

Update information in these files in preparation for the forthcoming
1.2.0 release.

Delete inappropriate svn:executable property

Clarify directions and also prepare for 1.2.0 release by referring to that
release, specifically.
