230 abstract config file parsing

[anthonyjlau]

If a change is made in a configuration file, then every notebook that uses that configuration file has to be changed. In order to centralize the process and make it easier to change configuration files, the R/config.R file will store "get" functions that get the fields from the config files. These get functions can be used in place of the hard coded variable assignments. It will also make it easier to update changes to config files as only the functions in R/config.R need to be updated.

Looks fine to me, documentation seems good enough for what it does.
