cutat() should be able to handle partial dendrograms

The cutat method check for a fully hierarchical community decomposition. However, the leading.eigenvector method do not return a FULL hierarchy, so it does not work with it. Is it a bogue ? If no, is there another solution to get the communities at a given level for leading.eigenvector.community ?

Yes, it is not really a bug, I simply forgot about it. Will be done in the next release. There were workarounds on the igraph-help mailing list, AFAIR.

Similarly multilevel.community does not return a full hierarchy, but would still be useful to visualize as a dendrogram.
