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.

        #Run clang modernize check using utility script which allow to process the code in parallel (only on Applications directory)
        python run-clang-tidy.py -clang-tidy-binary ~/software/clang+llvm-3.8.0-x86_64-linux-gnu-ubuntu-14.04/bin/clang-tidy -checks=-*,modernize-use-override -header-filter=/home/grizonnetm/projets/otb/src/OTB/Modules/Modules/Applications/.*/include/.* -j8 -fix -p ~/projets/otb/bin/release/OTB-clang3.8/ ~/projets/otb/src/OTB/Modules/Applications/*/app/*.cxx  > ~/temporary/run-clang-tidy-app-log.txt

        #Replace override by ITK macro (to maintain compat with c++98) in Modules/Applications
        find . -type f -print -name "*.cxx" |xargs perl -pi -e 's/\ override/\ ITK_OVERRIDE/g'

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.

Renamed sources <classname>2.h to <classname>.h and so on. Suppressed otbAtmosphericCorrectionParametersTo6SAtmosphericRadiativeTerms class. Added otbRadiometryCorrectionParametersToAtmosphericRadiativeTerms class instead. Tried to make those classes more reliable and more similar : otbReflectanceToSurfaceReflectanceImageFilter otbSurfaceAdjacencyEffectCorrectionSchemeFilter otbSurfaceReflectanceToReflectanceFilter. Warning : Task on otbAtmosphericEffects class not finished. Test about this class is still deactivated.

by default no adjency effect is computed (as previous even if the checkbox is set by default
correct some strange mistake about the name of parameters

for information in prevous version it is UInt16

support of user's parameters in optical calibration application
add filters for luminance to image, reflectance to luminance, reflectance to image
add related tests

ENH: clarify OpticalCalibration app by using parameter clamp instead of noclamp which was disturbing
