Introduction: langinfo

It can be tricky to figure out which language code is associated with which language, given the multiplicity of language code systems. 

<a href="http://en.wikipedia.org/wiki/Language_code">Wikipedia: Language code</a>

With this in mind, I would like to create a module (and eventually, a web service), which simply returns all available information. Here is background information on the sources I want to include:

**ISO 639-1** is the first part of the ISO 639 international-standard language-code family. It consists of 136 two-letter codes used to identify the world's major languages. These codes are a useful international shorthand for indicating languages. For example:

* English is represented by en
* German is represented by de (from the endonym Deutsch)
* Japanese is represented by ja (even though its endonym is Nihongo)

**ISO 639-2** is the second part of the ISO 639 standard, which lists codes for the representation of the names of languages. The three-letter codes given for each language in this part of the standard are referred to as "Alpha-3" codes. There are 464 language codes in the list.
