- this makes it possible to perform additional operations
  on surface values that have been previously sampled.

- support vectorField for weighting operations.

- reduce overhead by avoiding creation of weight fields, Sf fields
  and combined surface geometries unless they are actually required.

- extend some similar concepts and operations to volFieldValue

- handle sourcing bashrc with a relative path (issue #383)
- handle sourcing from bash and zsh.
  Still need manual intervention when sourcing dash, sh, or ksh.
- replace grep in etc/cshrc with sed only
- logical instead of physical path for WM_PROJECT_DIR (issue #431).
  Doesn't seem to be possible for csh/tcsh.

  * Continue using physical locations when comparing directories,
    but not for the top-level FOAM_INST_DIR, WM_PROJECT_DIR.

- relocate WM_CC, WM_CXX overrides from etc/config.*/compiler
  to etc/config.*/settings to ensure that they are left untouched
  when etc/config.sh/compiler is sourced while making third-party
  packages (eg, gcc, llvm, CGAL).

- provide fallback FOAM_TUTORIALS setting in RunFunctions

STYLE: remove "~OpenFOAM" fallback as being too rare, non-obvious

- use -name test before -type test to avoid calling stat(2) on every file.
- use -delete instead of -exec rm to avoid forking

boundaryRadiationProperties: updating to new format
dynamicMeshDict and snappyHexMeshDict in utorials/multiphase/interDyMFoam/RAS/motorBike to follow Mattijs Git lab id 381

- collects the log information only, without running any cases.
  This can be useful if the user has terminated the test prematurely
  but nonetheless wishes to summarize the log output.

- fast means of ensuring we are only testing what is contained in the
  repository

- regression introduced by a7195288

STYLE: add meaningful solid names for some stl files

ENH: InjectedParticleDistributionInjection  model - added protection for the case of zero particles; updated tutorial scripts.  See #363

BUG: Tutorial updates - updated rhoSimpleFoam thermo to use rhoThermo after commit a7c8d1cf - see #355

Bounding thermo.rho in rhoPorousSimpleFoam.
Changing initial time step in externalSolarLoad tutorial.
Commenting out momemtun source term in steamInjection which causes problems

ENH: Added tutorials to show extraction of particle data from eulerian cases and subsequent injjection via lagrangian cases

ENH: outletMappedUniformInlet BC - Cp only calculated for patch and not entire domain; input keywords updated for consistency
