#' `strex`: extra string manipulation functions
#'
#' There are some things that I wish were easier with the `stringr` or `stringi`
#' packages. The foremost of these is the extraction of numbers from strings.
#' `stringr` makes you figure out the regex for yourself; `strex` takes care of
#' this for you. There are many more useful functionalities in `strex`. In
#' particular, there's a `match_arg()` function which is more flexible than the
#' base `match.arg()`. Contributions to this package are encouraged: it is
#' intended as a miscellany of string manipulation functions which cannot be
#' found in `stringi` or `stringr`.
