Typescript declaration for WebAssembly JS API
NOTE: Node.js v8.0.0 is the first version that will support WebAssembly MVP. Since it's not yet released we assume its been downloaded or compiled locally and the executable is ../node/node. According to this v8.0.0 should be released on May 30th, 2017.
I tested by compiling node from sources on master branch at sha1 c68da89694b1ff4682131ed6b825e596188cc4ed
