Benchmarking

[blue-jaye-121]

Description Of Changes

This pull requests incorporates a benchmarks folder into the root of MetPy. Within this folder is configuration for Airspeed Velocity, an open source Python benchmarking software, the benchmarks folder which contains the benchmarking files, the Jenkinsfile and Dockerfile required for the Jenkins instance to run the benchmarks weekly, scripts to make the benchmarking process easier for the Jenkins instance, and an artificial 4D dataset used as benchmarking data.
Additionally, the docs folder will include a new page under the developers guide heading to explain the benchmarking setup and where to see the results.

Checklist

• Fully documented

[blue-jaye-121]

The Build Docs failure is due to the results repository not being set up; once that gets set up it should be good to go

This looks really good! Just a few minor comments/suggestions.
