Title: Luke: adds the ability to combine granules

- Primitive combination of granules
- Moves the granule classes into the init file for easier imports

You may now import the granule wrappers from `pyon.ion.granule` directly:
```
from pyon.ion.granule import RecordDictionaryTool, TaxyTool, build_granule, combine_granules
```
