##-----------------------------##
Version 1.1
##-----------------------------##

Done:
- in functions.py changed def create_sorted_endpointlist(intervals) to make it faster
- changed mwis.py

- added pk_tools

Effect:
- speed-up

- show the best near-optimal pseudoknots

##-----------------------------##
Version 1.2
##-----------------------------##

Done:
- kissing hairpins
- global structure

Effect:
- prediction of kissing hairpins

- show the best near-optimal pseudoknots and kissing hairpins

- show the predicted global structure

Bugfixes:
- allowed overlap of 1nt at junction for pseudoknots with interrupted stems (pk_construction.py)

##-----------------------------##
Version 1.2.1
##-----------------------------##

Done:
- takes FASTA file with multiple sequences as input

##-----------------------------##
Version 1.3
##-----------------------------##

Done:
- implemented dynamic programming algorithm to speed up recursive secondary 
  structure element search for pseudoknot/kissing hairpin candidates
- general cleaning up
