\DustemWrap Plugins description
\Plugin code is dustem_plugin_PLUGIN_NAME.pro
\SCOPES are:
\     ADD_SED: the output of the plugin function is to be added to the intensity SED
\     ADD_EXT: the output of the plugin function is to be added to the intensity Extinction SED
\     ADD_POLSED: the output of the plugin function is to be added to the intensity POLarizationSED
\     ADD_POLEXT: the output of the plugin function is to be added to the intensity POLarizationSED Extinction SED
\     MODIFY : Plugin only modifies dust model variables
\Caution: scope(s) could also be defined inside the plugin, as a returned keyword ....
