// Usage:
// str_find(str,pattern,[last],[all],[start])
// Description:
// Searches input string `str` for the string `pattern` and returns the index or indices of the matches in `str`.
// By default str_find() returns the index of the first match in `str`. If `last` is true then it returns the index of the last match.
// Searches input string `str` for the string `pattern` and returns the index or indices of the matches in `str`.
// By default `str_find()` returns the index of the first match in `str`. If `last` is true then it returns the index of the last match.
// If the pattern is the empty string the first match is at zero and the last match is the last character of the `str`.
// If `start` is set then the search begins at index start, working either forward and backward from that position. If you set `start`
// and `last` is true then the search will find the pattern if it begins at index `start`. If no match exists, returns undef.
// If you set `all` to true then all str_find() returns all of the matches in a list, or an empty list if there are no matches.
// and `last` is true then the search will find the pattern if it begins at index `start`. If no match exists, returns `undef`.
// If you set `all` to true then `str_find()` returns all of the matches in a list, or an empty list if there are no matches.
// Arguments:
// str = String to search.
// pattern = string pattern to search for
