Implement a @timer decorator that wraps a function and prints its execution time. The decorator must support any args and kwargs. The test harness receives a list of function calls (each ['name', args, kwargs]) and expects a list of booleans indicating the timer worked.
Summary
Wrap any function to capture how long it takes.
