Yeah, I've been forgetting to document that.

First row is reserved for the column headers (as in, its ignored)

First column is the contacts name, second column is the contacts phone number, all other columns are ignored if they exist

The directory "~/.dialcentral/contacts" is scanned for supported files

Other file backends can be created and csv can be made more flexible, its just this met a specific need of mine without fighting against APIs for working with other stuff.
