Potential feature?

I've been working on a version of extractFormants.py which is more user-friendly in batch mode, as it reads speaker background information from a master csv file rather than depending on user input or individual .speaker files. The csv should be located in `/bin` and be of the format:
`SubjectID,Name,Age,Sex,Ethnicity,YearsOfSchool,Nbrhood,Year`

Since I'm developing this in response to a specific Penn/PNC need right now (we want to rerun the PNC but the system Ingrid left behind is broken in multiple ways), the current version will probably break if the input is not from the PNC. Ideally I see this being generalized to other file naming conventions and included in the main program as an option.
