  - patchFields now get mapped (instead of created)
  - with -consistent it now maps all patches except for processor ones (they are
    the only ones that are processor-local)
  - all constraint patches get evaluated after mapping to bring them up to date.

dictionary files of a particular name and extracts entries of a
particular keyword, sorting results into a unique list.

For example,
    foamSearch $FOAM_TUTORIALS laplacianSchemes.default fvSchemes

produces...
    default         Gauss linear corrected;
    default         Gauss linear limited corrected 0.33;
    default         Gauss linear limited corrected 0.5;
    default         Gauss linear orthogonal;
    default         Gauss linear uncorrected;
    default         none;

Uses the fantastic foamDictionary utility.
