Graph operations

Graph operations such as linear paths merging, multiplication of segments and other are provided. These operations are implemented in analogy to those provided by the Ruby library RGFA. As RGFA only handles GFA1 graphs, only dovetail overlaps are considered as connections. A detailed description of the operation can be found in Gonnella and Kurtz (2016). More information about the single operations are found in the method documentation of the submodules of GraphOperations.
