#ConvertBackAndForth(strings_in, to_punycode) ⇒ Object
Function takes the list of strings and returns them in the converted format. Unicode to Punycode or Punycode to Unicode (param to_punycode). It uses a cache of already-converted strings.

#DocodeDomainNames(encoded_domain_names) ⇒ Array<String>
Decodes the list of domain names to their Unicode representation. This function is similar to DecodePunycodes but it works with every string as a domain name (that means every domain name is parsed by dots and separately evaluated).
