Add an alias for a matrix map.
Create a templated method in the MeshModel and IOMesh to automatically
cast the underlying mesh.

Create an interpolate() method in the VegaVolumetricMesh class to
interpolate surface of the underlying volumetric mesh with an external
surface mesh and clean up the interface.

Create a computeGravity() method in the VegaVolumetricMesh class
to compute gravity forces.

Refactor getVelocity() method in DeformableSceneObject and add a
variable to hold the gravity vector.

Refactor SceneObject. Add SceneModelRenderDelegate render delegate to
take care of renderign operations for this model. Create visual,
physics and collision model variables.

Remove render delegates from the StaticSceneObject, this is now handled
by it base class.

Add storage for the gravity force in VegaFEMDeformableSceneObject and
initialized properly. Compute internal force by multiplying K*positions
instead of calling the vega function.

Refactor DefaultSimulator, VegaFEMModelSimulator. This class will be
marked obsolete soon.

* Remove custom renderers
* Remove local storage for vertices
* Documenting

Small format changes all over the place.

Refactor ObjectSimulator.

classes. Also create a SimulationManager in charge of
running the simulation.

module.

- Also replace GL/glew by vtk_glew in Core/RenderDetail
- Remove empty first line in those

This module implements forward and backward Euler methods.

ENH: Add unit tests

ENH: Implement Newton's method. Used in the backward Euler method.

Add test for backward euler.

Fix MacOSX compilation error.

BUG: Make sure row major sparse containers are used
for all matrix computations.

Clean up interfaces, fix linking errors and transfer implementations
to cpp files.

Documents methods and variables. Clean solvers test.

Adding more documentation. Clean solver tests and interfaces.

Fix discrepancies in iterative solvers errors. Add more documentation.

VRPNDeviceServer did not properly setting framework termination flags
VRPNDeviceServer was also wrapping vrpn_Connection in a shared_ptr,
this was causing a double delete because vrpn_ConnectionManager
cleans up after connections made with vrpn_create_server_connection()

Add namespace to matrices.

Closes #61

Removing RenderDelegates, OpenGLRenderer, OpenGLViewer

- need glew.h in Core/RenderDetail for GLint
- need to link against Geometry in AVMNidus
- remove duplicated library in Rendering

- Remove RenderDetail::setTextureFilename() and co.
- Remove MeshModel::addTexture()
- Remove SurfaceMesh::assignTexture() and co.
- Use RenderDetail::addTexture()

Still need to assign texture in model?

This is to complete the use of renderFaces()

The 3ds file loading and attachment  of VAO for the tangents
for 3DS file are working fine now.

The renderdetail has been changed to accommodate these modifications.
The wet shader shader code is a bit modified.

Clean-up of the code is needed

Needed for custom shader attribute declarations such as tangents.

Camera scope tip bending works!

witht he VRPN interface.

Work on Integrate ToolCoupler with ObjectSimulartor
to implement haptics rendering.

Also enable and test force feedback.

to couple devices and models.

Add VRPN generic server device.

SimMedTK is using VRPN compiling properly.
Most of the VRPN stuff is compiling, but linking has some issues.
Somehow VRPN is adding libs that doesn't exist to the VS project for
linking. WIP Adds basic reading functionality from a networked
phantom omni.  Some misc changes happened in this commitsuch as some
namespace changes and framework start up and shutdown flow. Added a
vrpnPhantomController.  Abstracted out renderCube a little because
it gets used in other places. Fixed a few compiler warnings

Many other cmake improvements.

Fix GLEW/GLU dependency mess.

Set build configuration variables and pass down to to superbuild
external projects.

1. Removing GLEW external project. Glew is now
built with vtk, in order to use it just include
the vtk use file and add the vtkglew library
to the target link directive.

2. BUILD_SHARED_LIBS is now forced to be OFF for
Windows MSVC builds.

Build external shared libs in order to avoid linking issues in windows.

Also abstracted out some of the RTT code and put it in the example lib.
