Adding SO version to shared libs
Extended the marching cube algorithm.

The algorithm is now run on the 8 vertex of the current cube returning
many more surface normals (in possibly both directions for thin
objects).
Merge github.com:OctoMap/octomap into intersect
Reintroduced commented warnings.
Fixed includes.
Merge pull request #61 from fmder/fix-QGLViewer-includes

Fixed octovis include from PR #56
Merge pull request #60 from fmder/devel

Refactored the marching cube procedure
Removing warning for unknown space in castRay(), extending docs
Merge branch 'devel' of github.com:OctoMap/octomap into devel
dynamicEDT3D: install CMake module under share/dynamicEDT3D/

dynamicEDT3D was the only subproject installing its CMake module files
under lib/cmake/.
This patch cleans this up, making dynamicEDT3D installation consistent with
the octomap and octovis ones.
dynamicEDT3D: rename CMake module file names

dynamicEDT3D was the only subproject naming its CMake module files
<project name>Config.cmake.
This patch cleans this up, using the <project name>-config.cmake pattern;
so make dynamicEDT3D consistent with what is done for octomap and octovis.
cmake: offer CMake modules with no hard-coded path

Hardcoding absolute install paths in the CMake module files totally
breaks the cross-compilation: it makes impossible to be used in a
sysroot because the hardcoded paths are the ones of the target, whereas
they should point to the sysroot location. This tootally breaks the
CMake FIND_ROOT_PATH mechanism designed to handle cross-compilation.

This patch introduces a new CMake variable: NO_ABSOLUTE_PATH_IN_MODULE,
which, when set on the cmake command-line, will enable the installation
of the CMake module files using the CMake primitives find_library and
find_path to set the libraries and headers' locations, instead of
hard-coding them.

Thus, this patch adds non-templated CMake module files for octomap,
dynamicEDT3D and octovis for the non hard-coded path version of the
modules.

In any way, only the installed CMake module files are changed. The
templated ones are still needed for combined package build.

The non hard-coded path version of the modules are only installed when
NO_ABSOLUTE_PATH_IN_MODULE is set; by default the existing behavior
remains unchanged to keep honoring the behavior described in [1].
