Stress testing application

This is a simple stress testing application.

It compare the solutions in ans.cpp and check.cpp and report the running time.

It also reports errors e.g. TLE/RTE/MLE.

Requires C++17 (for <filesystem>),boost::process.

INSTALLATION:

Run g++ (or other compiler) tester.cpp -o tester.

USAGE:

The program accepts four arguments: ./tester nt wt ml result_file, with nt being the number of tests, wt being the time limit (in ms), ml being the memory limit in MB (not MiB!), and result_file is the file to output results. ml only counts the resident set size, so programs can allocate a lot of memory but if they're mostly unused pages, the reported memory usage can be small. nt defaults to 100, wt defaults to 1000, ml defaults to 256 and result_file defaults to ./result.out (can be changed in the code).
