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)
