In our recent publication, we changed some terminology to be closer to graph theory, see e.g. here for a simple introduction. To be consistent, we need to do some lightweight renaming in the code:

• PartialFlowGraph (PFGs) -> TransposeFlowGraph (TFGs), every occurrence, e.g., class names, java doc etc. This is because there is no such thing as a partial flow graph, but what we represent (a single sink with directed edges) is closer to a transpose rooted directed graph / flow graph.
• FlowGraph -> FlowGraphs or something similar like flow graph collection, or other if you have any ideas. This is because this class only represents a collection of independent actual flow graphs and does not represent a flow graph itself (because it has multiple root elements).
