// Library used for writing tests, must be included once for definitions and
// once for the `main()` function.
//
// DOCUMENTATION
// Expect(expr)
// Macro that will return early if the expression is false, calling
// `tb_shutdown()` to save the terminal. It will also print the expression
// and line on which it occurred for convenience
//
// test_functions TestFunctions
// Global variable containing the function (test). This array is
// 0-terminated.
//
// TESTFUNC()
// Macro for adding functions to TestFunctions array conveniently.
//
// tb_get_cell(x, y)
// Function
//
// EXAMPLE
// #define TEST_IMPL
// #include "test.h"
//
// bool FooTest()
// {
// Expect(0 == 1);
// return true;
// }
//
// test_functions TestFunctions[] = {
// TESTFUNC(FooTest),
// {0}
// }
//
// int main(int Argc, int Argv)
// {
// Test(Argc, Argv);
