This PR includes the following set of usability enhancements for the Tartarus package:

Installation/Usability/Performance

• Reliable set of dependencies identified
• Dockerfile & pre-built image created to provide users with working environment out of the box
• Reliable Conda env created
• Benchmarking script created and baked into docker image to run out of the box
  • Will take advantage of multi-processing if available to significantly reduce run-time
  • Users simply mount the data location into the container and the benchmarking will be performed automatically

Documentation

• Read-the-docs integration implemented
• API documentation generated directly from source doc strings
• Benchmark and task overviews written
