Caching Graph Adapter

You can use CachingGraphAdapter to cache certain nodes.

This is great for:

1. Iterating during development, where you don't want to recompute certain expensive function calls.
2. Providing some lightweight means to control recomputation in production, by controlling whether a “cached file” exists or not.

For iterating during development, the general process would be:

1. Write your functions.
2. Mark them with tag(cache="SERIALIZATION_FORMAT")
3. Use the CachingGraphAdapter and pass that to the Driver to turn on caching for these functions. a. If at any point in your development you need to re-run a cached node, you can pass its name to the adapter in the force_compute argument. Then, this node and its downstream nodes will be computed instead of loaded from cache.
4. When no longer required, you can just skip (3) and any caching behavior will be skipped.
