  Trims tokens and omits empty tokens.

  The given {@code delimiters} string can consist of any number of delimiter characters. Each of
  those characters can be used to separate tokens. A delimiter is always a single character; for
  multi-character delimiters, consider using {@link #delimitedListToStringArray}.
  
  @param str the {@code String} to tokenize
  @param delimiters the delimiter characters, assembled as a {@code String} (each of the
  characters is individually considered as a delimiter)
  @return an array of the tokens
