* Think of this as cordova-node, which would be simliar to cordova-android
* or cordova-browser. The purpose of this module is to enable testing
* of a plugin's JavaScript interface.
*
* When this module is first required, it will insert a global cordova
* instance, which can hijack cordova-specific commands within the pluin's
* implementation.
*
* Remember to require this module before the plugin that you want to test.
*
* Example:
*
* var cordova = require('./helper/cordova'),
* myPlugin = require('../www/myPlugin');
