DArray can store edges now
Fix aspectJ file
Hashmap stores Edges now
DHashSet for Nodes
More robust equality checks
Move all class information to a dedicated container
Relaxed type hierarchy once more to allow combinations of weighted and unweighted elements (weighted node with unweighted edges and vice versa)
Less warnings
Bug fix in DArray
* Better parsing of Integers
* a common method for getting the opposite end of an edge
* hashCode for Node corrected, to not rely upon more than the index (fixes contains() checks for hash based data structures)

Tiny addition to ensure proper reading
More generators
