Implemented reading settings from config file ftsort now outputs total runtime in ms and peak virtual memory usage Added some error handling Added documenation to tape_config.h Changed catch2 cmake dependency to be resolved using FetchContent Added generate_input test binary to generate big input tape data sets Header inclusion path changed to _include_ directory, so that tapelib has to be explicitly specified in include directrives
