TODO.md

• Fix Unhandled Promise rejections (see yarn test)
• Find a way to write readable tests
• Split randomtests into meaningful files
• Try to remove some unsafe any casts
• Add invalidate to Cache
• Add top-level invalidate. Should invalidate a set of queries
• I don't think this is needed anymore: Add topo-sort to top-level invalidate
• Add command(cmd: Fetch<A, L, P>, invalidates: Record<K, ObservableQ>). Implement the old runCommand as the result of command.run()
• Add support for Strategy (and maybe some default ones)
• Start porting some real world usages as tests
• Rewrite Products to be labelled products (structs) instead of tuples. So that we can e.g. reuse it as command named dependencies. Refer to https://github.com/gcanti/fp-ts-contrib/blob/master/src/sequenceS.ts (similar typing strategy)
• Add /react folder, basically including react-avenger with necessary changes
