/**
 * class iface_export_plugin
 * This a the abstract interface for an export plugin of importexport
 * 
 * You need to implement this class in 
 * EGW_INCLUDE_ROOT/appname/inc/importexport/class.export_<type>.inc.php
 * to attend the importexport framwork with your export.
 * 
 * NOTE: This is an easy interface, cause plugins live in theire own 
 * space. Means that they are responsible for generating a defintion AND 
 * working on that definition.
 * So this interface just garanties the interaction with userinterfaces. It
 * has nothing to do with datatypes.
 * 
 * JS:
 * required function in opener:
 * 
 * 
 * // returns array of identifiers
 * // NOTE: identifiers need to b
 * get_selection(); 
 *
 * get_selector();  //returns array
