* scratch adding histogram to image views Histograms should come from some sort of histogram service. This is currently just a POC. * custom logger implementation w/o spdlog * missing cmake file * fix tests * use operator<< over direct stream exposure * rm print header * add threading test + refactor towards interface libraries omits the need for =target_include_directories= calls /everywhere/ * rm print header * rm constexpr * templated thread_pool * fix doxyfile * default enable doc building * czi reader refactor * rm erroneous include expression * clang-format * single lib include with PUBLIC visibility * compile imgui stdlib * clang format * documentation update centralize `LogLevelToString` to `ILog.hpp` update docs and examples
