Add Inline PHPDoc

[mvriel]

From the current PSR:

Specific Tags MAY have an "Inline PHPDoc" section at the end of the "Tag"
definition. An "Inline PHPDoc" is a "PHPDoc" element enclosed in braces ({, }) and is present at the end of a "Tag" sequence unless specified otherwise in a
"Tag" definition, the "Inline PHPDoc" element MUST replace any description that
COULD have been provided.

An example can be the @method tag. This tag may be augmented using an
"Inline PHPDoc" to provide additional information regarding the parameters,
return value or any other tag supported by functions and methods.

Example

/**
 * @method integer MyMagicMethod(string $argument1) {
 *     This is the short description for MyMagicMethod.
 *
 *     @param string $argument1
 *
 *     @return integer
 * }
 */
 class MyMagicClass
 {
     ...
 }
