-- These new algorithms are more powerful than the restricted diamond merging algoriths, in that they can merge nodes with multiple incoming and outgoing edges. Together the splitter + merger algorithms will correctly merge many more cases than the original headless and tailless diamond merger.
-- Refactored haplotype caller infrastructure into graphs package, code cleanup
-- Cleanup new merging / splitting algorithms, with proper docs and unit tests
-- Fix bug in zipping of linear chains. Because the multiplicity can be 0, protect ourselves with a max function call
-- Fix BaseEdge.max unit test
-- Add docs and some more unit tests
-- Move error correct from DeBruijnGraph to DeBruijnAssembler
-- Replaced uses of System.out.println with logger.info
-- Don't make multiplicity == 0 nodes look like they should be pruned
-- Fix toString of Path
