Oops, yes; I think these should have been renamed just like every other instance below.
How shall we handle this @jdinan? Do you think it's eligible for a doc edit?
This is a continuation of the Bundles proposal, so closes the #481 pull request. Sessions are a generalization of Bundles, so users can pass hints for context optimization that go beyond just chaining/bundling. There is more discussion on this API design in the original ticket, #189.
As usual, I appreciate any feedback - thanks in advance!
