/**
 * interface for an obstruction for use by the ObstructRadioModelPlugin class
 *
 * Note the constructors of the concrete classes should take a string that will
 *      be a comma separated list of the params needed, where the first param
 *      should be ignored, as it will be the class name
 *      This will allow for easy loading from a file.
