(transient solvers) and corrected paths to the new location of the turbulence models.

This allows the constructions of applications which are independent of the particular
type of turbulence modelling.

 - use new HashSet capabilities and sortedOrder function
 - make STL format a MeshedSurface instead of an UnsortedMeshedSurface for
   better (MeshedSurface) reader efficiency

 - added global operator|, operator& and operator^
 - can construct from table of contents of another HashTable

  - now works as expected with transfer() and assignment from other Lists
  - shrink() method : clears indices and returns underlying List

 - changed template<class List> to template<class ListType> for better
   distinction between List as class and as template type

 - operator+=  : add in the listed keys
 - operator-=  : remove the listed keys
 - operator&=  : intersection of keys
 - added xfer constructor (just in case)
 - moved labelHashSet typedef to HashSet.H, for consistency with the
   wordHashSet typedef being there and since it is used so often

handling of "uniform", "mixed" and "polygonal" face lists.  Now converts
.cas files as well as .msh files.

PackedList with (const UList<label>&) instead of (const labelList&)
