checkMesh -writeFields does not check correctness

Functionality to add/problem to solve

checkMesh -writeFields '(BANANA)'

will happily run and not give any indication about illegal input. Attached file checks.

@mark : happy with this?

checkMesh.C

added feature label

Likely more like this. Funnily enough, we don't have a subtraction operator.

wordHashSet selectedFields;

if (args.found("writeFields"))
{
    selectedFields = args.getList<word>("writeFields");
    wordHashSet badFields(selectedFields);
    badFields -= allFields;

    if (!badFields.empty())
    {
        FatalErrorInFunction
            << "Illegal field(s) " << flatOutput(badFields.sortedToc()) << nl
            << "Valid fields are " << flatOutput(allFields.sortedToc()) << nl
            << exit(FatalError);
    }  
}
else if (args.found("writeAllFields"))
{
    selectedFields = allFields;
}
