Differences to JS version

• rx/from accepts ClojureScript sequences and IWatchables (= Atoms)
• Every object satisfying either Fn or IFn can be used with operators in
  addition to normal JS functions, e.g. (rx/filter obs #{:lol :bal})
• Operator functions (e.g. predicates and transform functions) receive only the
  mapped/tested values. If you need to access event indexes as well, use :all-args
  meta flag, e.g.
  ```clj
  (-> …
  (rx/map (fn [x i] (+ x i))) ; ATTENTION! i == undefined
  …)

(-> …
(rx/map ^:all-args (fn [x i] (+ x i))) ; now works
…)
```
