[lenaorobei]

Rule

PHPDoc formatting for classes and interfaces.

Acceptance Criteria:

• Sniff covers described on DevDocs requirements:

Classes and interfaces should have a short description that is a human-understandable intention of the class.
If the short description adds no additional information beyond what the type name already supplies, the short description must be omitted.

• Rule covered by unit test.

<severity>5</severity>
<type>warning</type>
