Corridor LandXML to include the true corridor & associated objects.

[Lisa_Pohlmeyer]

Currently the LandXML file of the corridor doesn't include the actual corridor itself, which I found by accident.  I had assumed it did.  What is currently included is a limited data set including Alignments, Profiles and Surfaces that are associated with the corridor.  All the items used to create the corridor should be included, assemblies, feature lines, etc.
