Create Baseline Performance Benchmark; Apply Initial Optimizations Using Numba

[jboarman]

We need an initial set of timings captured to establish a baseline for where we stand now for each augmentation.

Once we have that baseline, we should also take a first pass at optimizing using Numba to optimize loops. A separate issue will capture other types of improvements, such as leveraging GPUs and other techniques.
