- Fix workflow for PBD in SceneManager.cpp. Add/modify related functions for
PbdObject/PbdRigidObject/VirtualCoupleingPBDObject. It should work for the
most general case where collision/physics/visual meshes are different from
each other.
- Add LineMesh class and LineMeshRenderDelegate. Add support for LineMesh
class in imstkGeometry, imstkMesh, imstkRenderDelegate.

- Fix a bug for computeBoundingBox() in imstkMesh.
- Fix a bug for applying mapping in TetraTriangleMap.
- Fix a bug for computing the center of tetra in TetraTriangleMap.

	-Create PbdRigidObject class for objects that are not deformable but need
	to interact with deformable pbd objects.
	-Create VirtualCouplingPbdObject class, which is inherted from
	PbdRigidObject and TrackingController. The physics and colliding
	geometry(mesh) need to be translate/rotate manually to interact
	with deformable objects, which is different from existing
	VirtualCouplingObject class.

PBD examples not working properly due to issue related to mesh normals.

Conflicts:
	Base/Scene/imstkCollisionGraph.h
	Examples/Sandbox/main.cpp

Enforces style and place holders for comments in the pbd related code files

Style corrections2



See merge request !84

Add haptic device. Need to run in simulation mode, but rendering mesh in simulation mode is very low and results in huge amount of warnings

Adds basic plot generator scripts for vectors for Matlab and Matlibplot

Style enforcement and add comments over the entire code

Add OR Scene Objects and human models. Only one model can be assigned
texture now. Add test cases in Sandbox.

Deformable body sprint

Merging the deformable body sprint into refactoring branch

See merge request !81

Adds updateFunction to the NL system. Some style cleanup.

Trigger compilation error on macOSx

Vega filename was hardcoded in DeformableBodyModel.

In VegaMeshReader, keep a pointer to the vega mesh
within the volumetricMesh class, and use it when
initialising the deformable body model.

InsertNextTypedTuple needs to return a value or
compilation error on windows.

After rebasing on dynamics-sprint, the following
errors appeared:
- change from VecNf to VectorF
- wrongfully placed 'virtual' in MassSpringForceModel
- wrongfully placed '#endif' in MassSpringForceModel
- missing include in NonLinearSolver
- error in constructor in NonLinearSystem
- error in Eigen include in TimeIntegrator
- error in VTK remote address in External_VTK.cmake

Move force models implementation to ccp files
