Added new restraint infrastructure
Added MolecularRestraints
Added ObjectRestraints
Added RestraintStamp
Updated thermodynamic integration to use ObjectRestraints
Added Quaternion mathematics for twist swing decompositions
Significantly updated RestWriter and RestReader to use dump-like files
Added selections for x, y, and z coordinates of atoms
Removed monolithic Restraints class
Fixed a few bugs in gradients of Euler angles in DirectionalAtom and RigidBody
Added some rotational capabilities to prinicpalAxisCalculator

Adding restraint keywords to Globals

Adding options to RNEMD for selecting particular StuntDoubles

Returned old LD forces to SMIPDForceManager.

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.

Massive update to do virials (both atomic and cutoff-group) correctly.
The rigid body constraint contributions had been missing and this was
masked by the use of cutoff groups...

fixing a wrapVector problem in staticProps, also making Shifted force
and electrostatic damping the default behavior

fixed the half self term for wolf electrostatics and OOPSE now chooses a cutoff radius dependent alpha for damped electrostatics

Massive changes preparing for release of OOPSE-4: The main difference
is that the new MD file format (.md, .dump, .eor) now contains meta-data
information along with the configuration information.

Added simulation box dipole moment accumulation for the purposes of calculating dielectric constants

Adding spherical boundary conditions to LD integrator

refactor Hydrodynamics module.

Removed MixingRule from Globals. Handled by forceField now.

filepp can not handle multiple line macro, just convert multiple line macro into single line macro.

instead of printing to std::cout, throwing an exception when error is found.

Fix parsing error in OptionSectionParser

parsing by filepp

ForceField optional parameters....

Added a keyword and ability to output forces and torques

changing how we deal with summation and screening methods

Customized StatWriter is working

Change error message in Globals

added default restraint spring constants into Globals

Added support for skinThickness keyword to Globals.

some fixes but even more breaking (cutting out the old way to do reaction field)

adding c-side interface to change cutoff Policy

adding keyword printPressureTensor

NPAT is working

adding NPAT and NPrT integrators

using map to replace link list

Dunno

merging new_design branch into OOPSE-2.0

Import of OOPSE v. 2.0
