List of all steps

[dmikhalin]

Problem to Solve

It could be useful to have a list of all possible steps with descriptions for some of them.

• When we add a new step it is simpler to check if this step already exists in one file than in all feature-files.
• Some steps are not self-describing, especially if they have a table with parameters (e.g. "uniquely identify answer concepts").
• Some steps could be spelled in different ways (e.g. with/without verb ending).

Proposed Solution

The list itself could be auto-generated (but descriptions need to be added by hand, obviously).
