Provides a clean mechanism to run the lagrangian family of solvers without
a cloud

Changed the evaluation of omega to be a function of both omega in the viscous
sublayer and omega in the log region

- Using parcel chemical enthalpy to update cloud chemical enthalpy transfer
  instead of total parcel enthalpy.
- Added functionality to allow enthalpy transfer to be user-controlled,
  either using latent heat, or instanteous enthalpy difference

Added missing operators, and converted polys to be molar-intensive
to enable mixing using existing molar-weighted strategy

avoid accumulation of the name during copy and clone.

- also PackedBoolList.get(x) == 1 can be written without the ==
  comparison since the unsigned -> bool conversion is fast

- provides a convenient (and lazy) means of removing entries

- resize with factor 2 as per DynamicList

allow switch/bool values for writeCompression in system/controlDict

- eg,
    writeCompression false; or writeCompression uncompressed;
    writeCompression true;  or writeCompression compressed;

improves consistency with other controlDict parameters

- compatibility:
  * 'polySpline' and 'simpleSpline' accepted
  * detect and discard end tangent specifications

- a BSpline is also included (eg, for future support of NURBS), but is
  not selectable from blockMesh since it really isn't as nice as the
  Catmull-Rom (ie, doesn't *exactly* go through each point).

triangle, from:

http://en.wikipedia.org/wiki/Inertia_tensor_of_triangle

Adding the ability to calculate the inertia tensor of a polygon face
by summing the triangle inertias.

Added a test application to draw a test face with its principal
axes and moments of inertia.

- also looks reasonable and doesn't deviate much from Catmull-Rom
