Async is a set of functions for working with asynchronous blocks in Objective-C.

Project/AsyncTests.xcodeproj contains a simple set of tests that demonstrate how to use the library.

• Include Async.h in your project.
• All Async functions are class-level methods on the Async object.
• Sets of blocks are passed in as an NSArray.
• These blocks always have success and failure callback blocks which conclude the asynchronous function.
• Blocks may additionally receive and return a parameter depending on the method used
• All Async functions have a final success and failure block. If any one block fails, failure() will be called. If not, succcess() is called

• series: run a set of blocks in sequential order
• parallel: run a set of blocks in parallel
• eachSeries: runs a block in series with every item in an array
• eachParallel: runs a block in parallel with every item in an array
• mapParallel: runs a block in parallel with every item in an array, collecting all the return values
• mapSeries: runs a block in series with every item in an array, collecting all the return values
• repeatUntilSuccess: repeat a block until it succeeds or maxAttempts is reached
• waterfall: run a set of blocks in series, passing the return value of a block to the next block
