Process forms are views displayed to users. They may be configured for the
User Task model elements. There are several process form types:
Jmix view — a user interface view.
Input dialog — a form is generated in the runtime when a user starts a process or completes a user task. Form fields are defined in the process model.
No form — a process should be started programmatically.
Custom — used if you need to render a form in a non-standard way.
