The SeriesTask run a task collection(array) one by one.

Task    = require 'task-registry'
tasks   = require 'task-registry-series'
register= Task.register

class OneTask
  register OneTask
  executeSync: (aOptions)->
    # the aOptions is the default options object of the task if no arguments passed.
    aOptions = 0 unless isNumber aOptions
    aOptions+1

class TwoTask
  register TwoTask
  executeSync: (aOptions)->
    aOptions = 0 unless isNumber aOptions
    aOptions+2

result = tasks.execSync
  pipeline: true
  tasks: [
    One: 1 # call OneTask with 1 argument
  , 'Two'  # call Two
  ]  # the result should be 4

tasks.execSync(aOptions)/task.exec(aOptions, done)

• aOptions (Object|Array|String): it's a tasks if it's array. it's a task name if it's string.
  • pipeline (Boolean): whether the pass the result as a pipeline. default to false.

  • If false, Each task will be called with the arguments, and each may return a value.
  • tasks (ArrayOf String|Object): the tasks to run.
    • Object:
      • key: it's the task name
      • value: it's the arugments object to be passed.
