Corrected the geometry directory name from "triSurface" to "geometry".

Resolves bug-report https://bugs.openfoam.org/view.php?id=2529

This class does not simply rotate the coordinate system is also changes
it from Cartesian to cylindrical which is not clear from the original name.

We plan to rewrite the coordinateRotation classes to be
coordinateTransformation classes and massively simplify the interface
from the currently unintelligible mess.

Resolves issues with probes and findRefCell for meshes in which all cell face-pyramids are positive.

+ Move most of the octree searching functionality from triSurfaceMesh into
  triSurfaceSearch. Much of it was duplicated anyway.
+ Add triSurfaceRegionSearch, which constructs an octree for each region in
  a surface and performs searches on specified regions only.

coordinate systems
Modifying constructors from dictionary of coordinateSystem class (no
default type)
Adding localAxesRotation type. It constructs a axes-rotation tensor on each
cell centre.
Adding functionality to coordinateRotation blase class (transformTensor,
transformVector, etc)

- Re-located mapped point patches
- Updated mapped patch write
- deprecated directMapped in favour of mapped
- updated resulting dependancies - apps/libs/tuts
