/***************************************************************
 *
 * This is a refactored version of class tx_lib_configurations.
 * What has been changed?
 * - there is no parent class anymore to reduce complexity
 * - all data is stored at instance variable _dataStore
 * - this class is the dataholder of any cObj in the plugin
 * - provides an instance of formatter class
 * - provides a dataholder named $_viewdata used to transfer any
 *   data from controller to view
 * Configuration is the meant to be a central point for all parts
 * of MVC Pattern.
 * The API of this class has not been changed. So it can be used,
 * as always.
 ***************************************************************/

/**
 * Object to load, hold, transport and deliver all or some TypoScript-Setup of an extension.
 *
 * It is very usefull to store all configuration of an extension into this object and to
 * access it easily in any place you need it all over your extension. Usefull functions are already provided.
 * More will be added by time. You also may provide your own functions in inherited classes.
 *
 * Configuration can be loaded into this object by 3 different functions, typically in the following order:
 *
 * 1.) loadTypoScript():          loads TS down from a given node of the TS tree into the object.
 * 2.) loadConfiguration():       loads an already redered TS array, typically from local configuration
 * 3.) loadFlexForm():            loads flexform data (xml or array) into the object
 *
 * Details:
 *
 * 1.) TS directly from a setup path: example 'plugin.tx_myextension.configuration.'. Please mind that there is
 *     a DOT at the end of the path, because it has subelements. You may set the setupPath in a class variable
 *     of a derived class or alternatively provide it as parameter.
 *
 * 2.) An configuration array of rendered TypoScript like it is handeled to the main function of plugins by the
 *     outer framework: tx_myextension_controller->main($out, $configurationArray). This should be called after 1.)
 *     to give the possibility to overwrite global settings.
 *
 * 3.) The last load typically comes from the flexform to give the enduser the possibilty for finegrained selections.
