//'@title Decode Geohashes
//'@description \code{gh_decode} takes geohashes and turns them back into
//'latitude/longitude pairs, with an associated margin of error for each value.
//'
//'@param hashes a character vector of geohashes.
//'
//'@return a data.frame of four columns; "lat", "lng", "lat_error" and "lng_error"
//'
//'@seealso \code{\link{gh_encode}} for generating geohashes, and
//'\code{\link{gh_neighbours}} for identifying the neighbouring hash boxes
//'to a geohash.
//'
//'@examples
//'# A simple example:
//'gh_encode(lat = 42.60498046875, lng = -5.60302734375, precision = 5)
//'#[1] "ezs42"
//'
//'gh_decode("ezs42")
//'# lat lng lat_error lng_error
