====== Tasks Draft ======
There should be a "Task" model that has a minimum of fields:

Mandatory:
  * created, modified timestamps
  * task name / title

Optional:
  * Patient reference
  * Device reference
  * due date/time
  * task description

It has to be determined if Tasks should be a module that depends on others, or (better?) creates an API for other modules to create tasks.
Another possibility would be that Task is an abstract model, and other modules can inherit ''Task'' and make special "extensions" to it like ''patient'', ''device'' etc.
