gcoder: Tools for accessing the Google Maps API

#' gcoder: Tools for accessing the Google Maps API
#'
#' \pkg{gcoder}
#' The main functions in this package are \code{\link{drive_time}}
#' (used for calculating distances between physical addresses) and
#' \code{\link{geocode_url}} (used for estimating lat/long coordinates
#' of a physical address). Currently, Google provides scripts and functions written
#' in other languages (Python, Ruby, etc.) to generate the cryptogric signatures needed to
#' access the non-free Maps API, but does not offer a script for the R language
#' (hence the motivation for this package's authorship).

#' Google's paid accounts have much larger quota limits than the "standard_api" and,
#' for this reason, gcoder may be useful for indivuals needing to submit large batch
#' jobs to the Google Maps API from directly within R.
#' While the main benefit of this package is it's ability to generate properly
#' signed URLs with the \code{\link{hmac}} sha1 algorithm, it
#' also provides methods for accessing the standard API using a (free)
#' Google API key (see \href{https://developers.google.com/maps/documentation/javascript/get-api-key#get-an-api-key}{this page} to obtain a key).
