Nrel-hive

the first official open-source release of HIVE.

this patch to version 0.8 of HIVE adds some time step reporting features and allows hive-distributed to unify the scenario output directory suffix for separate hive runs.

this patch adds timestep-accumulated logging to hive v0.8 along with some minor changes.

this release adds the following features to hive:
- pooling physics
- allows for assigning a pooling trip _but not yet updating a pooling trip_
- no dispatcher implemented
- API for co-simulation with hive (__crank__ hive externally)
- naming changes in support of hive technical report
- fixes to support repositioning in hive-distributed

Includes a new batch runner to run multiple local hive simulations in parallel.

Usage is `hive-batch batch.config.yaml` where the config file enumerates the hive scenario files to run ([example](https://github.com/NREL/hive/blob/develop/hive/resources/defaults/sample.batch.yaml))
