Spec Steps

[tnunnink]

What if we change spec to be steps that are configurable. Possible steps are Filter, Select, and Verify. Each step can occur more than once. The output of one is the input to the next essentially.

Benefits:

• Allow multiple filters steps for narrowing search space based on data that passed previous step.
• Selection of properties (and nested tags) so that we can be more agnostic to the data coming into the verification step.
• I think would allow potential to reduce number of necessary specs.
• Much more flexibility obviously.

Cons:

• Type/data rework which would require migration and potential data loss if not handled.

I think this might make #35 unnecessary.

Instead of steps, just adding group number to criterion. This would let us separate filters into groups. Each group gets processed together to then pass along to the next to get the "steps" we were looking for. From the UI, we can just have a list per group in the filter section. Selection step would be lot of rework, and we would only need it for nested tags. We need to just figure out another approach for deeply selecting tag members. We also would only ever have one verification step. So, all things considered, we don't need steps but rather filter groups.
