transpiling to es5

fix #18

hi,

sorry but not sure exactly how you did transpile the lib.

Isn't there a pipeline to transpile from source to target?

What if someone later add a const, will you think about transpiling again?

Asking because the lib did fail for me in IE11 and was not easy to track down what was the cause, and don't want it to happen again, but the process here makes me feel it's likely to happen again

@slorber You are right. It can happen again. I can't even do it manually every time. So I added a transpiling pipeline. (#23). I hope that will be merged. 😄

great thanks for making this more sustainable ;)
