Open requested to merge github/fork/phcerdan/update_ITK_NULLPTR into master
This commit replaces occurences of the ITK_NULLPTR macro with nullptr. This one-liner was used to perform the update:
git grep -l "ITK_NULLPTR" | fgrep -v CMakeLists.txt |fgrep -v .cmake | xargs sed -i '' -e "s/ITK_NULLPTR/nullptr/g"
It was adapted from https://github.com/InsightSoftwareConsortium/ITK/blob/master/Utilities/ITKv5Preparation/ReplaceITK_NULLPTRMacroNames.sh
