* This module executes JavaScript using Google's V8 JavaScript engine.
*
* It extends the available JavaScript classes with the following FS related classes;
* CoreDB Adds features to access the core DB (SQLite) in FreeSWITCH. (on request only)
* CURL Adds some extra methods for CURL access. (on request only)
* DTMF Object that holds information about a DTMF event.
* Event Object that holds information about a FreeSWITCH event.
* File Class to reflect the Spidermonkey built-in class "File". Not yet implemented! (on request only)
* FileIO Simple class for basic file IO.
* ODBC Adds features to access any ODBC available database in the system. (on request only)
* PCRE Adds features to do regexp using the PCRE implementeation.
* Request Class for extra features during API call from FS (using 'jsapi' function). This class cannot be constructed from JS code!
* The Request class is only availble when started from 'jsapi' FS command, and only inside the predefined variable 'request'.
* Session Main FS class, includes all functions to handle a session.
* Socket Class for communicating over a TCP/IP socket. (on request only)
* TeleTone Class used to play tones to a FS channel. (on request only)
* XML XML parsing class, using the features from switch_xml. (on request only)
* CoreDB Adds features to access the core DB (SQLite) in FreeSWITCH. (on request only)
* CURL Adds some extra methods for CURL access. (on request only)
* DTMF Object that holds information about a DTMF event.
* Event Object that holds information about a FreeSWITCH event.

* Some of the classes above are available on request only, using the command [use('Class');] before using the class for the first time.
