esri_webfeaturelayer_extract (AutoLISP)

This AutoLISP function converts a web feature layer to a document feature layer. Any web feature layer edits are abandoned and all features present on the layer remain. The AutoCAD layer name of the web feature layer will be modified to drop the prefix of "esri_" and the definition query of the resulting document feature layer will be set to that new layer name. Likewise any sublayers of the parent will have definition queries set to the new AutoCAD layer names for each sub feature layer.
