going directly to develop 0.5.0-SNAPSHOT with destructive API-changes
Reason is, the map/unmap orgy in the original flambo not only bloats the dependency tree of RDDs, but also every map transformation DESTROYS THE PARTITIONER INFORMATION!!!
* This version keeps the partitioner (see api_test.clj: l.531-538)
* This version uses fewer intermediate vectors (esp. if you use the destructuring function wrappers)
make map-to-pair and flat-map-to-pair behave like the other functions.
removed to narrow type hints.
* fix example (moved it to a new place to not clutter my output when I use the library)
* formatted project.clj (sorry, this makes it a bit unclear what changed in the first place when moving the library)
* updated README to at least reflect the changes, but there's lots of work to be done here
