Mark Olesen 9e6683f7bc ENH: add conditionals to #eval (string to scalar)
Example,

     ($radius > 10) ? sin(degToRad(45)) : cos(degToRad(30))

- protect division and modulo against zero-divide.

- add scanner/parser debugging switches in the namespace,
  selectable as "stringToScalar". For example,

    debug parser:  foamDictionary -debug-switch stringToScalar=2
    debug scanner: foamDictionary -debug-switch stringToScalar=4
    debug both:    foamDictionary -debug-switch stringToScalar=6
