Document #each list as |blah| etc

[rclai]

Wouldn't it be incredibly valuable to document this use of #each? It would really be a great alternative (and less of an eye-sore) than to have to do ../parentField, especially when nesting #each's.

Looks like we missed these docs when implementing. We should document this. Anyone who wants to take a crack at this, the best location is somewhere around here:

A small question, the |foo bar| is only valid for #each , or we can think it is a generic array syntax for all custom helper? For example maybe we can do this: {{#myLoop |a b c|}} and it should be cool.

Any helper can use providing they pass the proper args. I'm not in front of
a computer right now but the each impl should provide example.

We also need to improve the documentation on how to write helpers for block parameters as well. @ErisDS has a good high level summary in #907 that covers a lot of the things that we will need to document.
