Introducing Workbench data manager in order to align the central/local DB switching scheme of BMS API to that of BMS applications based on the workbench "program" in context.
Initial commit: Implemented central/local DB switching based on selected workbench program. API methods now operate against the central/local DB of the selected program, similar to BMS.
Refactored common environment configuration out into a separate component.
Refactored "program in context" resolution logic into a separate component.
Cleaned up variable names for the ontology and study browser ui. Logging set to debug.
Trivial changes to Eclipse config.
Updated README as per the recent changes to align API with BMS program based DB switching scheme.
