// Basically, it looks for a list of decimal numbers embedded in the
// string and uses the first three as degree, minutes and seconds.  The
// presence of a "S" or "W character indicates that the result is in a
// hemisphere where the final answer must be negated.  Non-number
// characters are treated as whitespace separating numbers.
//
// So there are lots of bogus strings you can feed it to get a bogus
// answer, but that's not surprising.  It does, however, correctly parse
// all the well-formed strings I can thing of to feed it.  I've tried all
// the following:
//
// 37°54.204' N
// N37 54 12
// 37°54'12"
// 37.9034
