compareTo method removed
Adapted towards new transformation/class hierarchy
Adapted to new transformation interface/class hierarchy
Initial version of the decentralized spectral graph drawing algorithm
due to Dell'Amico
Some corrections
Progress indications for the routing added
Debug code for hyperbolic embeddings added
Handling of ID Spaces for PIE and PrefixEmbedding added
Set the number of nodes to the number of nodes in the first element of
list
Simple Extension of Greedy Routing for Virtual Tree Prefix Embedding:
In case of a local minimum forward the message to the parent in the
tree
only output progrees of routing if debug set to true
variable reduce added, to control the behaviour of Bidirectional
workaround as the code didn't compile
Spanning tree which remembers the traversal order during its
construction
Added multiple spanning tree embeddings
IdentifierSpaces for PrefixEmbeding and its variants
MaxNormIdentifier using shorts
ignore debug lines in wot file
trees do not need to actually span the graph
