Extend ResourceFinder and GraphIndexer interfaces to support pagination
-----------------------------------------------------------------------

                 Key: CLEREZZA-678
                 URL: https://issues.apache.org/jira/browse/CLEREZZA-678
             Project: Clerezza
          Issue Type: Improvement
    Affects Versions: 0.2-incubating
            Reporter: Daniel Spicar
            Assignee: Daniel Spicar
            Priority: Minor


the findResources methods should support pagination by extending the interface with (from,
to) arguments. From is inclusive, to is exclusive.

Background: Currently the idea of the maxhits parameter in GraphIndexer has been misunderstood.
It can be used to support pagination in this manner:
First get results from 0-20 with maxhits 20. Then the user wants to see results from 20-40,
so the same IndexSearcher can be used with maxhits set to 40. Because the IndexSearcher already
holds results 0-19 in memory, only results 20-39 are loaded from the index.
