Various fixes required to compile OpenMD with the MS Visual C++ compiler

Individual ForceField classes have been removed (they were essentially
all duplicates anyway).  

ForceField has moved to brains, and since only one force field is in
play at any time, the ForceFieldFactory and Register methods have been
removed.  

Added files for fcc and pentagonal nanorod builders. Updated runMe in samples/builders to include nanorod builders.

fixing the build system

Merging changes from old branch into development branch

small changes

Updating visitor architecture to something a bit more modern

Fixed a missing cstdio include

Added some logic to print out a special pair distance as a column in
the stat file.  To use this feature, use taggedAtomPair = "0, 10" and
printTaggedPairDistance = "true" in the md file.  Then, the distance
between integrableObjects 0 and 10 will be computed and printed in
the stat file on each statWrite.

Committing changes made to AtomVisitor to render xyz2pov scenes

Support for printPosOnly in Dump2XYZ.

fixed a build problem...  GB_12b_ratio no longer exists (replaced with BG_l).

testing GB, removing CM drift in Langevin Dynamics, fixing a memory
leak, adding a visitor

adding a gay-berne switch to Dump2XYZ

End of the Link --> List
Return of the Oject-Oriented
replace yacc/lex parser with antlr parser

adding AtomNameVisitor

Couple of changes for TAP water.  Need to parametrize.

fixed the wrapping

adding IndexFinder which is used to select the molecules; Seperate ElectrostaticAtomTypesSectionParser into
ChargeAtomTypesSectionParser and MultipoleAtomTypesSectionParser;remove print dipole option from Dump2XYZ;

fix compilation problem for g++ 3.4

adding LipidTransVisitor, GofXyz is working now

IgnoreVisitor and XYZVisitor now use selection library

moved Package variable into subdirectory makefiles to speed up
the building process

merging new_design branch into OOPSE-2.0

replace old GebericData with  new GenericData

change Makefile to relative path

Import of OOPSE v. 2.0
