###Adding a new Evidence Source

1. Pick a short name for the evidence source; no spaces, starting with a letter
2. Create an Objective-C class called FooEvidenceSource in the same style as the other sources. It should inherit from one of these: | | EvidenceSource | GenericEvidenceSource | LoopingEvidenceSource | GenericLoopingEvidenceSource (the simplest) | | Use custom nib? | |Yes | No | Yes | No | | Use simple loop? | No | No | Yes | Yes |
