return nodes individually for browser/bloom

• allow to filter relationships (with wildcards and by direction)
• add filters on counts to filter out less relevant or too dense nodes / rels
• figure out a better api
• move from parameters to config
• support projections (virtual graphs as source for grouping)
• optional computed grouping property, e.g. write cypher that returns nodes and the property to group by e.g. match (m:Movie)-->(g:Genre) return g.name as group, m as node
• build a visual tool on top, similar to: https://github.com/dbs-leipzig/gradoop_demo#graph-grouping
• option to remove self relationships
• option to remove orphan nodes
