Check for node / edge mixins
Additional checks for mixins
Write and read edge types -- this is necessary for non-matching node and edge types
More tests on add / remove
DArray: better handling of null
Wrap more calls into assertions, resulting in a bugfix
Better default weight, also conform with the String parsing constructor
New interfaces that help us creating instances
Decoupled edges and nodes and a new constructor for weighted edges
Restructured exceptions
Another test case to catch duplicate insertions
Searching the proper edge constructor needs tons of time, so cache it, please!
HashCodes are killing me...
GraphTester now checking for multiple additions of an element with different weights
Batch equality and tests about it
Move weight type deduction to GDS
Equality checks for batches and updates to allow testing of write/read
Tiny changes here and there, mostly debugging and refactoring
Extended batch test for a deeper equality check of written batches and their influence onto graphs
Reorder statements to be more precise about the flow
