Leverage new rustc wasm features This commit leverages two new attributes in the Rust compiler, `#[wasm_custom_section]` and `#[wasm_import_module]`. These two attributes allow removing a lot of hacks found in wasm-bindgen and also allows removing the requirement of `wasm-opt` to remove the unused data sections. This does require two new nightly features but we already required the `proc_macro` nightly feature and these will hopefully be stabilized before that feature! 2018-03-14 14:33:53 -07:00			`#![feature(proc_macro, wasm_custom_section, wasm_import_module)]`
Rewrite the README using Webpack Right now Webpack probably has the most mature support for loading wasm modules, so let's show off how to do that! Additionally this commits hello world as an example to the repository. 2018-03-02 20:11:30 -08:00
