meshlab

Meshlab project cloned in entirety but only using two files: "Parser" and "Scanner" in order to reformat .wrl/.x3dv files as .xml

Automatic repo clone

Meshlab repo is automatically cloned. Users who haven't opted-in to VRML support won't be burdened with the extra download volume.

To update the git commit hash pulled down, modify Meshlab_GIT_TAG in file code/CMakeLists.txt; it is not expected that the sole files of interest "Parser" and "Scanner" will change frequently, if at all, going forward
