BaseSegmentInfoFormatTestCase
Abstract class to do basic tests for si format. NOTE: This test focuses on the si impl, nothing else. The stretch goal is for this test to be so thorough in testing a new si format that if this test passes, then all Lucene tests should also pass. Ie, if there is some bug in a given si Format that this test fails to catch then this test needs to be improved!
