Tests cleanup: skip closing EMF if it failed to create
Removing experiment: standalone FullTextManager
HSEARCH-1354 Javadoc improvements
HSEARCH-1354 Moving DuplicateDocumentIdTest to TypeMetadataTest. Test itself does not need ORM infrastructure
HSEARCH-1354 Refactoring of test harness. Test based on Junit 3 and 4 were using the same base class which can potentially cause problems

 Introducing a base class for each JUnit version and extracting ORM resource management into a separate class.
HSEARCH-1354 Adjusting to SearchTestCase#getSessions to SearchTestCase#getSessionFactory rename.

Also moving tests into a more appropriate directory
HSEARCH-1354 Typo
HSEARCH-1354 Adjusting old Junit 3 based test cases extending SearchTestCase to changes in this class

 Renaming SearchTestCase#getSessions to SearchTestCase#getSessionFactory
 Disallowing setCfg( null ) to rebuild configuration and introducing explicit forceConfigurationRebuild()
 Direct access to the session - getSession() must be used
 Import cleanups
HSEARCH-1354 Making JPATestCase a JUnit 4 only test base class
HSEARCH-1354 Junit 4 based tests extend now SearchTestCaseJUnit4
HSEARCH-1354 Some related test cleanups
HSEARCH-1354 Fixing error handling during indexing for mass indexer and adding test case
HSEARCH-1374 Project import error on Windows: com.sun:tools dependency missing
HSEARCH-1377 Polish some minor concurrency mistakes
HSEARCH-1378 Including/exluding bounds correctly for numeric range queries created with the DSL
HSEARCH-1354 Fixing wrong import in OptimizerPerformanceTest and making sure that super#setup() is called in setup() of ReaderPerformance
HSEARCH-1354 Improving on design of SearchTestCase and SearchTestCaseJUnit 4 by lazily initializing TestResourceManager. This way other methods as setup() might be called before calling super#setup()
