This module parallels elm/core's Task module.
Pull requests are welcome to add any functions that are missing.
The functions here produce SimulatedTaskss instead of Taskss
and SimulatedEffects instead of Cmds, which are meant to be used
to help you implement the function to provide when using ProgramTest.withSimulatedEffects.

Chain together a task and a callback.
A task that succeeds immediately when run.
A task that fails immediately when run.
Transform a task.
Transform the error value.
