Changes to enable storing task environment in metadata

[edeno]

@jguides Questions for you:

1. How does this interact with the yaml? Does one specify the task environment there?
2. What happens if it is not specified?

[jguides]

@edeno, 1) yes. The task environment can be specified as a field in the tasks section of the yaml file, for example

tasks:

• task_name: forkTrack_centerAlternation_HaightLeft_twoSecondDelay task_description: centerAlternation camera_id:
  • 2 task_epochs:
  • 4 task_environment: HaightLeft

2) If it's not specified, it should default to 'none'. I will test that this works by generating a new nwb file without the task environment specified.

In my original push, "environment" instead of "task_environment" was searched for in the yaml file. For consistency, I'll change this to "task_environment" (as in the example above).
