- literal lookups only for expression strings

- code reduction for setExprFields.

- changed keyword "condition" to "fieldMask" (option -field-mask).
  This is a better description of its purpose and avoids possible
  naming ambiguities with functionObject triggers (for example)
  if we apply similar syntax elsewhere.

BUG: erroneous check in volumeExpr::parseDriver::isResultType()

- not triggered since this method is not used anywhere
  (may remove in future version)

- use FACE_DATA (was SURFACE_DATA) for similarity with polySurface

ENH: add expression value enumerations and traits

- simple enumeration of standard types (bool, label, scalar, vector)
  that can be used as a value type-code for internal bookkeeping.

GIT: relocate pTraits into general traits/ directory

- unused, generally fragile.

- snGrad, internalField, neighbourField.
  Functional use as per swak: "... + internalField(T) ..."

ENH: additional volume/patch expressions

- deltaT()

STYLE: rename exprDriverWriter -> fvExprDriverWriter

- the original class name was a misnomer since it holds a reference
  to fvExprDriver

BUG: expression faceToPoint/pointToFace definitions were flipped

ENH: refactor expression hierarchy and code style

- handle TimeState reference at the top-level for simpler derivations

- unified internal search parameters (cruft)

- use refPtr to simplify some logic.
- avoid copying field if an average will be used
- initialize geometric fields with a uniform value instead of Zero
- minor tweak of method names

- apply bugfix #1889 (longer description elsewhere)

- some support for "uniform" bool fields. Calculating an averaged
  value for a boolField does not work very well, but we simply define
  that the field average is 'true' when more than 1/2 of its values
  are true. Not exactly true, but allows templated definitions to work
  smoothly.

- additional output method writeValue().
  This outputs the single (uniform) value or the first value of the
  field.

- polymorphic field/result
