Description

Planned changes, primarily to allow us more flexibility in the future:

• Rename "tau_0" to "tau0"
• Mark LDAOptimizer trait sealed and DeveloperApi.
• Mark LDAOptimizer subclasses as final.
• Mark setOptimizer (the one taking an LDAOptimizer) and getOptimizer as DeveloperApi since we may need to change them in the future
