improve coverage

Fixes #333 
It's not a pretty diff, but it will put us back in the green.

Seems neat for simple cases but large objects are harder to read.

Example... I changed `TableId` to `Table` in the key of one object. I guess in that case, all the extra information is just noise.

To get mocha to work with power-assert you need to do a couple things:

Need to add:
``` js
"directories": {
  // This works for regular unit tests.
  "test": "test/",

  // I thought this would work but it doesn't for regression tests. 
  // Couldn't figure out how to get regression tests to work.
  "regression": "regression/" 
},
```
to this `package.json`.

And update the npm scripts "test" and "regression-test" to include `--require intelli-espower-loader`
