Removes a number of vertices from lines. The number of vertices removed is controlled by a weeding tolerance, which will be either (Filter Factor * Cleaning Tolerance) or (Filter Factor * value of Feature Tolerance Attribute). The latter is always used when it is valid and the Feature Tolerance attribute is specified. The larger the weeding tolerance, the more vertices will be removed.

Each feature that is output through the Cleaned port will have a new attribute "mrf_clean_status" added to specify whether the feature was modified, created, or unchanged in the cleaning process. The possible values of this attribute are "Modified", "Created" and "Original".
