Add reflect function wrapper to allow always passing iterations

[jtwebman]

Add reflect that wraps a function with a always passing callback and a object with error or value property set.

This is one way to solve issue #942.

👍 @megawac What do you think?

We're probably going to hold of on merging this until #996 is complete, though,

[jtwebman]

Should I add in a reflectAll helper as well?

[aearly]

Sure. It's pretty simple though -- async.reflectAll(tasks) vs. tasks.map(async.reflect).

[jtwebman]

Added reflectAll as well as rebased off master. I'll wait for the other PR to be merged in and then refactor for that.

[aearly]

You should be good to go for your refactoring. 👍

@jtwebman Any update? This is the last change for the 2.0 release.

[jtwebman]

@aearly I can get this in tomorrow for you. Been moving the family to Portland the last two weeks.

[aearly]

Ah, no rush. Worst case, we save it for 2.1.

[aearly]

@jtwebman How are things going? Should we save this for a later release?

[jtwebman]

Sorry about the delay, was down and out sick. Working on it tonight.

I an going to close this PR as I opened a new one for this as the files changed and merged freaked out. #1095
