replacement

A consistent, simple and easy to use set of wrappers around the
fantastic 'stringi' package. All function and argument names (and positions)
are consistent, all functions deal with "NA"'s and zero length vectors
in the same way, and the output from one function is easy to feed into
the input of another.
