/*
This class holds the run-time environment of the plasma
Search Engine. It's data forms a blackboard which can be used
to organize running jobs around the indexing algorithm.
The blackboard consist of the following entities:
- storage: one plasmaStore object with the url-based database
- configuration: initialized by properties once, then by external functions
- job queues: for parsing, condensing, indexing
