Support @extends, @implements, @uses

[arnaud-lb]

This adds support for the @extends, @implements, @uses tags. These tags can be used on a class-like to give type information about existing inheritance, implementations, or trait uses.

• @extends: Denotes that the class extends the given class with the given parameterized types
• @implements: Denotes that the class implements the given interface with the given parameterized types
• @uses: Denotes that the class uses the given trait with the given parameterized types

Grammar:

'@' ('extends' | 'implements' | 'uses') identifier '<' type (',' type)* '>'

Example:

<?php

/**
 * @template K
 * @template V
 *
 * @implements Collection<K,V>
 */
class Foo implements Collection {
}
