Default is OFF since we have issues configuring
it on Windows currently.

All projects output directories are now common in
the top level. This commit takes care of the
CMAKE_CONFIGURATION_TYPES for Visual Studio.

With this commit the Find_XXX.cmake files do not need
HINTS anymore since all targets are built in a same
directory known to CMAKE_LIBRARY_PATH, and all headers
directories are referenced in CMAKE_INCLUDE_PATH.

The scene needs to be paused, but not the viewer.

Also make Geometry class polymorphic by making its
destructor virtual.

Conflict existed within VTK.

Can directly used to create visual objects.

Also use unordered_map in SimulationManager.

This base class was needed for storing position and
orientation of the geometries. Those global transformation
can also be applied to discrete geometries, therefore
Geometry and AnalyticalGeometry classes were merged.

Was not applying the quaternion on the good side.

Core sprint

Include Core sprint branch into refactoring branch.

- CMake architecture / Superbuild
- Uncrustify for code style checking
- G3log for logging
- Core classes : SimulationManager, Module, & Scene

See merge request !79

Had to pass g3log_SOURCE_DIR from the superbuild to
the inner build to be able to find the librairies for
g3log in Findg3log.cmake.

./configure alond does not work on Windows. Needs to set
up the option `--host-`.

See https://github.com/uncrustify/uncrustify/blob/uncrustify-0.62/make_win32.sh#L11-L22

Make sure that we don't run into an error when uncrustify
is disabled, by providing info on how to set it up.

Also allow to skip uncrustify (not recommended).

Some newer commits of uncrustify bring in a new
configuration method for Uncrustify that makes the
cmake integration more difficult.

Also edited the PREFIX directory inside the Superbuild
directory

Use config based on https://gist.github.com/mkroman/1372117

- Still need to edit the configuration file
- Removed example target for kwstyle

- SetupForDevelopment is a bash script that will setup the git
environment for the user, by running setup scripts in SetupScripts
directory.
- SetupGitUser will assure that a conform name and email adress
are configured.
- SetupGitHooks will copy git hooks in the .git/hooks directory
- SuggestGitTips will suggest useful tips to configure git
- prepare-commit-msg is a git hook which will display the standard
prefixes that can be use for the commit summary
- commit-msg will ensure the commit message follows those standards
as well as some other basic rules

In the future we will incorporate KWStyle to check the code style
in the git pre-commit hook.
