dot2circ - convert ViennaRNA dotplots to circular base-pairing diagrams

example_calls.ipynb:
- Example calls for folding an RNA using RNAplfold, preparing the circos data files and finally calling circos for plotting.

TODO

create callable script
create galaxy tool definition file
update sequence plotting to accomodate different length RNAs (currently works for RNAs of up to ~300 nt)
