Baseline ignore annotation.

When this annotation is applied to a baselined element, the baseliner will ignore the annotated element when baselining against a baseline package whose version is less than the specified version. This means the annotated element will not produce a baselining mismatch. The correct baseline information about the element will be in the baseline report, but the element will not cause baselining to fail. When baselining against a baseline package whose version is greater than or equal to the specified version, this annotation is ignored and the annotated element will be included in the baselining.
