Module seed::gloo_timers

Dummy file reuqired by Rust's module system

Modules

callback	Callback-style timer APIs.
future	Future- and Stream-backed timers APIs.
sys	Raw bindings to the Javascript APIs we need, namely set(Timeout|Interval) and clear(Timeout|Interval). Depending on how rustwasm/wasm-bindgen#1046 is resolved, we may be able to remove this at a later date.
