Tracking strategies for Reflux.all

[spoike]

As detailed in #28 by @bripkens. The following strategies exist:

• trackLastCall (currently implemented in Join parallel listeners to one #28 for Reflux.all) - takes the last argument received for each
• trackFirstCall - takes the first argument received for each
• trackAllCalls - mashes all arguments together
• ensureEqualNumberOfCalls - throws error if something was called more than once before the promise was completed

[spoike]

If it's only these strategies available then we probably should expose them as seperate functions on Reflux.

• Reflux.all - trackLastCall
• Reflux.allLeading - trackFirstCall
• Reflux.allCalls - trackAllCalls
• Reflux.allStrict - ensureEqualNumberOfCalls

[spoike]

Probably call rename them to joinXyz instead of allXyz... If it makes more sense for someone reading the code?

• Reflux.all and Reflux.joinTrailing (alias) -> trackLastCall
• Reflux.joinLeading(...) -> trackFirstCall
• Reflux.joinRepeated(...) -> trackAllCalls
• Reflux.joinStrictly(...) -> ensureEqualNumberOfCalls

Thoughts?

[bripkens]

Separate functions sounds good. Especially since the function's interface (Reflux.all with multiple strategies) would otherwise become too complicated.

Here is a visual representation from baconJS of different join patterns. The most interesting ones are merge and combine.

This has been implemented in #92 so I'll close this.
