  +=== Adding progress reporting, retry and throttle control to collection concurrent operations
   +s_mach.concurrent+ allows modifying collection concurrent operations (+serially+, +concurrently+ or +workers+) to
   report progress, retry failures and limit iteration speed to a specific time period.
   
  
positive.code: * Overcomes some design limitations of the scala.concurrent library
  * Provides convenience methods for writing more readable, concise and DRY concurrent code such as +Future.get+, +Future.toTry+ and +Future.fold+
  
  == Include in SBT
  1. +s_mach.concurrent+ is currently compatible with only Scala 2.11 (but there are plans to add 2.10.4 support)
  2. Add to +build.sbt+ OR +~/.sbt/{verison}/build.sbt+

  === Tuple Concurrently
  When first using +Future+ with a for-comprehension, it is natural to assume the following will produce concurrent
  operation:
