Add assumption support to Javadoc of Parameterized
Add assumption support to Javadoc of Parameterized

Since 7111b9621997f6c660687b8ac04003398343ee3a we support assumptions in
@Parameters methods. This commit adds a description of this feature to
the Javadoc of the Parameterized runner so that people can discover the
new feature more easily.
