Breaks the string on the pattern, and returns an array of the tokens.
If the pattern contains capturing parentheses, then the text for each
of the substrings will also be returned. If the pattern does not match
anywhere in the string, then the whole string is returned as the first
token.
As a special case, the result of splitting the empty string "" is an
empty vector, not a vector containing a single string. The reason for
this special case is that being able to represent a empty vector is
typically more useful than consistent handling of empty elements. If
you do need to represent empty elements, you'll need to check for the
empty string before calling this function.
A pattern that can match empty strings splits string into separate
characters wherever it matches the empty string between characters.
For example splitting "ab c" using as a separator "\s*", you will get
"a", "b" and "c".
