Adds a "Returns" section with the description text.
This text should describe the return type and permissible range
of values. This tag is valid only in a doc comment for a method.
Omit @return for procedure and constructors; include it for all
other methods, even if its content is entirely redundant with
the method description. Having an explicit @return tag makes it
easier for someone to find the return value quickly. Whenever
possible, supply return values for special cases (such as specifying
the value returned when an out-of-bounds argument is supplied).
