Concurrency in high resource commands

[rjbohinski]

Note, I am not sure if the FIRST libraries provide their own implementation of this through their 'Command' and 'Subsustem' abstract classes.

Systems such as image processing can be resource intensive. By default, Java will pause execution of other code until the function returns. This can be harmful for the drive system as it may need to wait for an unrelated process to complete before it can handle the driver input.

Oracle provides great documentation on the topic.
