1.
--metascan segfaults when destroying the allscanlist.

2.
scanserver segfaults whith reflectances sometimes.
E.g.,

bin/scanserver -c 3500
and
bin/show -s 0 -e 1 -f riegl_txt --reflectance ~/dat/bremen_city --scanserver

or
bin/scanserver
and
bin/slam6D -s 0 -e 1 -f uosr dat --scanserver

3.
scan_red with panorama range image and cylindrical coordinates does
not work correctly.

4.
fast_normals does not work on SRI yet. Commented out.

5.
reflectance_reduced not in managedScan/scanserver

6.
normals not integrated managedScan/scanserver

7.
kdMeta/kdManaged does not support kNN nor range search yet

8.
Make our own knn efficient, then get rid of ANN ;-)
