-RM-368-MR-Buildings detection approaches using the Point Cloud Library

This ticket considers the buildings detection using the Point Cloud Library (http://pointclouds.org/). PCL by itself is a universal library for processing point clouds. Actually this library contains no special methods for buildings detection but this ticket currently tries to take advantage of the Region Growing Segmentation method (see http://pointclouds.org/documentation/tutorials/). It's a surface point segmentation method that gives a result of a fair quality.

At the moment the module "Surface detection by PCL" only uses that method to show up surfaces. There are no buildings detection methods. In future there could be methods that cut off ground, trees, fences and everything else. Afterwards buildings could be segmented using a region growing algorithm on point regions (voxels). The plugin only gives an overview on the possibilities of the Point Cloud Library Region Growing Segmentation. Further steps are postponed because of the work on the most recent surface detection algorithm.
