#' Fix invalid android version strings with assumed values
#' 
#' This function attmepts to fix invalid android version strings that are a 
#' single number. The fix makes the assumption that the number represents the
#' major version number of the release.  However, prior to Android 5.0 the major 
#' version number was shared across a number of releases:
#' i.e. 4.0 Ice Cream Sandwich, 4.1 Jellybean, and 4.4 KitKat.
#' See \href{https://source.android.com/setup/build-numbers}{Android: Codenames, Tags, and Build Numbers}
#' @param version_string A string indicating the major version number to be fixed
#' @param snap_to_min A logical value indicating whether the version number 
#' should snap to the minimum version for the given major value otherwise it
#' will snap to the latest known version for the major version number provided.
