Hmm, I'm having some trouble figuring out how code coverage dropped. It looks like the new test should exercise the added functionality, but maybe I'm overlooking something simple. EDIT: Turns out it was untested lines in the new test. |

* Functions should avoid being defined within another function body if possible * Naming consistency * Flow typing * Arrow functions with a single return statement should not use block format * Check typeof 'function' instead of non-falsey * filter(Boolean) to remove falsey values

I'm pretty new to flow, but shouldn't this be options??

Addresses #82
Checks to see if custom cache map has the required methods on initialization. The documentation just says it needs to be an object with a similar API to Map but the DataLoader only uses those 4 methods, so I figured it was okay to selectively check for those.
