      a map of name/value pairs

  - ### parse

    public Map<String,String> parse(String str, char[] separators)
    Parses a map of name/value pairs from the given string. Names are expected to be unique. Multiple separators may be specified and the earliest found in the input string is used.
    Parameters:
      `str` - the string that contains a sequence of name/value pairs
      `separators` - the name/value pairs separators
