yPlot Code

Documentation build (not complete, yet).

Document new build and use procedure.

Tweak.

Must autoload yplot (with plparseopts command) before referring to yplot
variable DRAW_LINEXY.

Initial commit of CMakeLists.txt file to help build and install the dynamic
documentation files.

STATUS: Many of the PostScript demo results now build correctly, but there
is more work to do to complete this.

Re-indent following emacs cmake mode rules.
Install static documentation files.

Cleanups to get rid of all warnings other than "may be uninitialized"

Remove .cvsignore files which are not needed by svn.

Generate documentation using yorick rather than yplot. No plotting
facilities are needed for this task so we should have made this change long
since, but the change is now mandatory since yplot no longer exists as a
separate executable.

Better instructions about how to enable the yorick extension that gets built
by "make" and installed by "make install".
