RNAdesign 1.5

• Adds a wrapper for RNARedPrint calld RPSampler which has a similar interface to the RNAblueprint DependencyGraphMT object.
• Adds design-redprint-multistate.py for boltzmann weighted sampling using RNARedPrint and multi-dimensional boltzmann sampling. Please cite the preprint: https://arxiv.org/abs/1804.00841
• Adds design-energyshift.py to target exact target energies for the specified input structures, also by using multi-dimensional boltzmann sampling. cite preprint: https://arxiv.org/abs/1804.00841
• Adds wrapper functions and a Design subclass for Hotknots (http://www.mybiosoftware.com/hotknots-2-0-predict-secondary-structures-rna-pseudoknots.html)
• Adds wrapper functions and a Design subclass for pKiss (https://bibiserv.cebitec.uni-bielefeld.de/pkiss)
• Adds a structure class to represent and manipulate an RNA secondary structure
• Bug fixes
