Complexity Analysis

PyBryt exposes its code complexity analysis tools so that they can be used to analyze blocks of code without necessitating the use of the annotation framework. These tools can be used to give students a way to test the complexity of their implementations, or just to analyze code complexity in a manner that is more reliable than using a timer.
