Implementation of Triangle-Triangle Intersection check.

- Based on the paper by Tomas Moller.
- Given two triangles, it returns a boolean indicating whether the
  triangles intersect each other.
- Test cases are specified as a list in a TriangleTriangleTest class, so
  that they can be re-used by the Triangle-Triangle contact calculation
  tests.
Adds LabJack data acquisition device, with limited functionality.

There are multiple models of LabJacks, which use various libraries.
This code supports the U3, U6, and UE9 via LabJackUD (high-level
driver) on Windows, and the U3 and U6 via exodriver (low-level driver)
on Linux or Mac.
This code uses Command/Response communication and supports digital
inputs, digital outputs, and timers (all modes including quadrature and
PWM).
All other functionality is not currently supported (e.g., streaming,
counters, analog in/out, and I2C).
Adds documentation to VisualTestCommon/ToolSquareTest.h.
Triangle-Triangle Contact Calculation implementation.

- New implementation of the Triangle-Triangle contact calculation.
- A new TriangleClipper class does the clipping against a given plane. It
  also helps to find the penetration depth given a plane.
- The class and the function (calculateContactTriangleTriangle) are in a
  separate header.
PhysicsManager, add ExcludedCollisionPairs

- Basic implementation of excluding CollisionPairs from the Physics
  pipeline.
- Add unit tests.
ExamplesStapling, exclude collisions

- Exclude collisions between wound and arm
- Exclude collisions between stapler and virtual teeth
Also search for LabJack's exodriver in /usr and /usr/lib
DcdCollision, erase only found collision pairs
LabJackDevice, pass setter arguments by reference.
LabJackDeviceTest, removes non-test.
Add a return value to remove warning
Updated Triangle-Triangle code to use boost.

- Replaced arrays to boost::container::static_vector.
- Introduced a more functional TriangleHelper and Plnae classes.
- edgeIntersection is refactored as a funciton to avoid code duplicates.
- Changed heraders to inl-h headers. The function declaration is now in
  Geometry.h
Fix linux64 warning in Vector/Matrix/Quat YamlConvert
Fix Linux64 warning by removing SolveAndInverse<Sparse>

It was not used and we are moving toward a completely dense storage with dedicated algorithm...coming soon.
Add run after build
MlcpPhysicsProblem, improve updateConstraint

- Wrapping the reference with Eigen::Ref prevents Eigen from producing
a copy of the passed matrix.
Optimized delete vertex in TriangleHelper.

- Reduces the number of copy to the left.
TriangleMeshTriangleMeshDcd, add verification

- Verify penetration points are coplanar
- Verify penetration point is within the triangle
- Verify penetration depth and normal minimally resolves
penetration
Fix bug in error message in example AddSphereFromInput
Merge branch 'master' of git.assembla.com:OpenSurgSim into fix/warningsLinux64
