Current situation

MGNLPER-72 basically provides the API to use different strategies to memorize periscope result search ranking.

Per default the module comes with the strategy to memorize the ranking for every user.
Plus it provides one other implementation to memorize the ranking per user, IF a user has the role ranker or superuser - which allows to control the number of users with their own distinct ranking network.

The "issue"

Currently, to changing the strategy requires a change in the module-descriptor of the periscope-result-ranker module. Such a change requires the build of a custom module, rebuilding the module or hacking into the jar-file ... and a redeployment of the webapp.

Aim

Provide a mechanism which allows "easy" configuration of the strategy. E.g. on the config. workspace under /modules/periscope-result-ranker/config.
