 FnQueue runs a list of functions, each passing their results to the dependent function in the list. However, if any of the functions pass an error to the callback, the next function is not executed and the main callback is immediately called with the error.
 
 Each dependency/argument must be named with the label of the dependent function in the `functionsList` (the first constructor argument).
-Each function with a dependency will be called with the result of the dependent function as expected. __(YES this is a fucking cool introspection!)__

 The global callback is called once, on the first error or at the end of the execution. A data object will be provided with the indexed result of the functions.
