base64serialize: Helpers for converting R objects to strings and back
Description
base64serialize() converts an R object into a string suitable for storing
in an environment variable. Use this function for encoding entire R objects
(such as OAuth tokens) so that they can be used in Travis builds.
base64unserialize() is the inverse operation to base64serialize().
Use this function in your tic.R to access the R object previously encoded
by base64serialize().
