kcorebip fully compatible with interactive mode

This release is fully compatible with the interactive mode, and so with bipartgraph (jgalgarra/bipartgraph).
input parameters that will be deprecated: displaylabelszig, labels_size. The function call may include both but have
no effect on the outcome.
ziggurathoriz_kcoremax_tails_expand is now deprecated, superseded by kcore1tail_disttocore
Parameter values of ziggurat_graph and polar_graph are returned by the functions. This feature is useful to store them for future simulations.

Polar plot improved, reduced node overlap.

This release include major improvements in the polar plot. Node distribution algorithm has been replaced and
now is deterministic, so angular position of each node does not change each time the script is run. Nodes may be unfilled, this feature in combination with node labelling provides a more insightful plot.

Minor improvements in ziggurat plot.

Release for Peerj paper

This was the release to work out the paper "Ranking of critical species to preserve the
functionality of mutualistic networks using the k-core decomposition"

Alpha release

This release does not support weighted ziggurats. It is the first working release for public usage. Compatible with the interactive mode
