  Name            :name          String   The name of the learning task
  Block types     :blocks        Any      Types of the blocks that are compatible with this task
  Category        :category      String   Kind of task, e.g. "supervised"
  Description     :description   String   More information about the learning task
  Learning task   :constructor   Any      Function instance to create a corresponding learning task.

Description: 
A registry for learning tasks. loading an entry will return a function that
  can be used to construct a LearningTask given blocks.

  taskfn = load(learningtasks(id))
  task = taskfn(blocks; kwargs...)

  Inspect ?taskfn for documentation on the arguments that the function
  accepts.

  See datarecipes to load these datasets in a format compatible with learning
  tasks.
