allow different unit for radius and center, put mode vector in the fit mode as an option (fit mode's input : ref image or vector file) get ride of the function trying to read the info of the input vector file in update, it is now only in execute this can easily be back in the update it is a subjectiv choice.

    Where available, use c++11 features to identify
    potential nullptr usage errors.

        clang-tidy tool can insert missing override keyword as a macro so that missing [optional] virtual identifiers can be easily added.

        build otb with clang 3.8 and use cmake option CMAKE_EXPORT_COMPILE_COMMANDS=ON. Most modules and third parties have been activated.

This patch is authored by Bas Couwenberg <sebastic@xs4all.nl>
from DebianGIS team. spelling errors were encountered when
updating OTB debian package for 5.2.1.
https://bugs.orfeo-toolbox.org/view.php?id=1143

This is a big one without much harm. It fixes incorrect spelling
and grammer when packaging OTB 5.0.0 and 5.2.0 for Debian.
Most of these changes are done by developers at DebianGIS.
For more info, I include the original patch header below.
Description: Fix some spelling errors to silence lintian
enabling  to concentrate on the real problem.
