This is a plugin registry that allows plugins to be loaded/registered in two ways: 1. Through an explicit call to ``.register(name, value)``. 2. By looking for other Python packages that are installed and provide a setuptools entry point group. When you create an instance of this class, provide the name of the entry point group to use:: reg = PluginRegister("my_entrypoint_group") zdict[str, str]entrypoint_err_messagesdict[str, Any]_global_settingsentry_point_groupr: plugin_typeIsPluginrr<c||_||turft|trQdt|jd}t |dt tt||_ n||_ d|_ d|_ i|_ i|_ |jj|_dS)a Create a PluginRegistry for a named entry point group.
