 In Toxygen plugin is single python (supported Python 3.0 - 3.4) module (.py file) and directory with data associated with it. 
 Every module must contain one class derived from PluginSuperClass defined in [plugin_super_class.py](/src/plugins/plugin_super_class.py). Instance of this class will be created by PluginLoader class (defined in [plugin_support.py](/src/plugin_support.py) ). This class can enable/disable plugins and send data to it.
