Reading a field(?) within a dictionary
 

I'm having some trouble reading some dictionary entries into a model I'm working on.

This is a lagrangian simulation, and within my reactingCloud1Properties dictionary, there is a subDict called localInteractionCoeffs (already defined as 'coeffDict()'). I cannot get the data within the sub dictionary below that ("patches"). It has '(' braces instead of '{', so it isn't a dictionary entry, right? Subdict doesn't work. However, the next level down, does contain dictionary entries, which I want. I just cannot seem to figure out what type of data this is so that I could say:

x = this->coeffDict().lookup("patches");

And then do another lookup or subdict to get values for a specific patch name (which I already know).

Any thoughts?
