/**
 * The base XML-API class
 *
 * The XML-API class allows for easy execution of cPanel XML-API calls.  The goal of this project is to create
 * an open source library that can be used for multiple types of applications.  This class relies on PHP5 compiled
 * with both curl and simplexml support.
 *
 * Making Calls with this class are done in the following steps:
 *
 * 1.) Instaniating the class:
 * $xmlapi = new xmlapi($host);
 *
 * 2.) Setting access credentials within the class via either set_password or set_hash:
 * $xmlapi->set_hash("username", $accessHash);
 * $xmlapi->set_password("username", "password");
 *
 * 3.) Execute a function
 * $xmlapi->listaccts();
