Hi all! We are about to merge [SMTK MR 2810](https://gitlab.kitware.com/cmb/smtk/-/merge_requests/2810), which allows SMTK to switch between `std::regex` and `boost::regex` (this will become more important as C++ is deprecating `std::regex`).

Going forward, this means you should include `"smtk/Regex.h"` instead of including `<regex>` or `<boost/regex.hpp>`.
