cosmetic: removed mention of no-longer-used options -analysis_topup and -job_topup from the docs
moved loading/saving of the collections into DBAdaptor module
Moved the caching from Hive.pm into the specific storable classes themselves (via Cacheable.pm) to better conform to Active Record pattern
api_change: renamed Hive::DBSQL::MetaContainer --> PipelineWideParametersAdaptor
bugfix: generate_graph should also be able to display pipelines without semaphores
another version of LongMult pipeline to test -wait_for rules
pulling in the -wait_for test
Do not assume any error is related to the format. Just display it as it is.
bugfix: make sure -wait_for is working properly again (do not auto-initialize Cacheable)
