Summary: Proposed changes to GAMESS-US Reader

Initial Comment:
Hi there,

I am a postdoc with Mark Gordon at Ames Lab and I have been hacking into Jmol 
recently with the goal of improving its ability to understand output from 
several methods.

Below you will find changes I have made based on the released 11.6 source.  I 
had started using the most recent SVN trunk, but there were some issues 
regarding antialiasing on the MAC that turned me away.

--Additions--
GamessUSReader.java: 
Can now read EFP1 water molecules for FRAGNAME=[H2ODFT/H2ORHF].  These 
potentials are currently available in GAMESS.  EFP2 potentials are not yet part 
of the release.  This works for any number of EFP molecules and also for 
optimizations.  There are more complete comments in the source.

--Changes--
GamessReader.java and GamessUSReader.java
I have built support for reading several more types of orbitals (closed shell 
only).  This required changes to GamessReader.java that allow for orbital 
reading where energy, occupation or symmetry are not present.
The changes I made allow for continuous addition of orbitals to the present 
model.  This means that in a single-point run where the "initial guess vectors" 
are printed along with an RHF (or anything else) for N orbitals, the first N 
orbitals will be the guess and N+1 to 2N orbitals will be the optimized RHF 
orbitals.  For an MCSCF calculation one may have up to three sets of orbitals 
(initial guess, MCSCF natural orbitals, MCSCF optimized orbitals).  I have left 
it so that the user would have to be aware of what order the orbitals appear 
the figure out the mo number to display the desired orbital.  (This may not 
work as expected in all cases.)  While I have not tested all possible 
calculation types, there are some comments about keywords for which the changes 
work.  

MoldenReader.java:
There were some MOLPRO-generated files that perhaps did not adhere strictly to 
the documented (albeit vague) standard on the MOLDEN website.

I have included several output files which may help understand these changes.


The files I want to include are too big to be uploaded here and are available 
at my website:

http://homepage.mac.com/albertdefusco/gamess.tar.bz2

The file is 968 KB.


I have had no prior experience with Java and apologize for the flagrant errors 
I have probably made.
