Crush and crash....yeah my mistake:) I went with wrong letter...:) thx:)

Oh, I accidentaly ommited that case... Right, the same problem was
considering Bellman's Ford, but this time I did one bad assumption and lost
it. Anyways, just changing keys to lists this time didn't do the trick,
because there was a problem during execution of isEulerian? method. Fleury
method ( used by Eulerian ) returns error, when it's given such graphs. I
will have to take a deeper look into it, as firstly I wanted to end the new
TSP implementation. Probably, it's not a big problem, will see....

Oh, right... so now it's obvious why tests went good everytime.... I'm glad
that by accident it helped to find a bug.

Interesting! Actually, now after spending some time coding in Tcl, I'm a bit
surprised, how it happened that Tcl was almost fully omitted during classes
at my University.... We was using Tcl scripts for example, when doing some
simulations on computer networks, but when it came to subjects about
programming in script languages, there was nothing about Tcl...weird.
