this is a new attempt to fix https://github.com/neo4j/spatial/issues/72
Create .travis.yml
removed http://tinkerpop.com/maven2 from list of repos because we get only 403 replies from there
Merge branch 'master' of github.com:amorgner/spatial
added surefire plugin section to make the add performance test pass (with 1G heap space)
modified heap size settings for tests, should be fast and don't crash VM
use a more unique name for lookup index; remove nodes from lookup index when they are removed from layer index
commit after each stepping loop in testAddPerformance
limit heap size to 1G
Support alternative port number on test so we can run tests even if normal server is installed and running on default port
Merge branch 'amorgner'
Removed warnings
Refactored to bring back the deleted GEOM_NEXT code, but in a developer explicit way. The default is to not use that code for performance reasons, but sometimes it is useful.
Refactored to move the GEOMETRIES and NEXT_GEOM relationships into OrderedEditableLayer so that it is much more explicit when to use these
