Routine Description:\r
\r
- Compare whether two names of languages are identical.\r
+ Compare the first language instance of two language codes, either could be a\r
+ single language code or a language code list. This function assume Language1\r
+ and Language2 has the same language code format, i.e. either ISO639-2 or RFC4646.\r

Arguments:\r
\r
- Language1 - Name of language 1\r

+ Language1 - The first language code to be tested.\r
+ Language2 - The second language code to be tested.\r
\r
Returns:\r
\r
- TRUE - same\r
- FALSE - not same\r
+ TRUE - Language code match.\r
+ FALSE - Language code mismatch.\r
