Added exports for smRenderingOculus.  Fixed the Oculus examples so they compile.  Also found a stray GLUT reference and removed it.

Added smGeometry to the exports list.  Also linked smGeometry to smRendering.

Implementation of penalty contact response

Added axis rendering. Also added arrow rendering (vectors can be visualized using smGLRenderer::drawArrow

by a mesh.

Enabled collision model rendering.  Re-named smViewer::draw to smViewer::render to avoid confusion.  Fixed a typo in renderCubeToTexture example.

Removed smDrawParam, and got rid of some smScene functions like registerScene.  Also removed Scene Iterators.

Changed surface mesh loader to reflect to vertex array resize call instead of reserve during initialization~

The rendering window now shows up in vega example. The simulator seems to be executing. added haptic event required later for demo. Modified the driver code to be same as in Demos project.

ToDO:
Get the mesh rendering through smSurfaceMesh up and running
debug Collision detection and Response algos.

Hacked up a bunch of the smVegaSceneObject and alike classes to get a building project.  Also completely pulled GLUT from CMake.

Modified vegaexample to use smVegaSceneObject and its child classes
Remove raw pointers

This branch provides exports in order for external project to easily find and use SimMedTK and its dependencies.

Pass BUILD_SHARED_LIBS to the cache in the super build configuration.

Some fixes for the Oculus examples and code in the framework that wasn't mainentenced in the previous merge with master

FIX: Prevent simmedtk_find_package from overwritting CMAKE_INCLUDE_PATH and CMAKE_LIBRARY_PATH on Windows
