To give it a spin you can do the following:
node index.js list
node index.js test "Tree Zig Zag" "command for executing your tree-zig-zag solution"
NOTE: your command will be dumped directly into terminal, so if it is a python file do ./tree_zig_zag.py
It maintains a clone of of the cli_tests repo in ~/.cfi, each folder is a problem, each problem contains unit tests [0-9]*.{input,ouput} It loads these in and runs unit tests asynchronously.
