Will Bainbridge 0da49126b4 multiphaseEuler: Function to extract wall boiling model properties
This function looks up wall boiling wall functions and collects and
writes out the following data:

  - Bubble departure diameter
  - Bubble departure frequency
  - Nucleation site density
  - Effective liquid fraction at the wall
  - Quenching heat flux
  - Evaporative heat flux

Example of function object specification:

    \verbatim
    writeWallBoilingProperties
    {
        type            wallBoilingProperties;
        functionObjectLibs ( "libmultiphaseEulerFoamFunctionObjects.so" );
        writeControl    writeTime;
        phase           liquid;
    }
    \endverbatim
