To verify the working of build_paramDict

[dinskid]

I've added code to build the parameter dictionary in #26
I've made use of ReExes to extract the parameters from the source code and used Julia's meta programming to convert them into julia objects.
Please verify the working of the code and suggest if there is any better way to do it.
I wasn't able to get the RE for extracting the params whenever nested () where there (I wasn't quite able to write recursive REs to do the same), so I used a rudimentary way to extract it.
FYI, in python we make use of inspect.
