Workflow and performance optimization for fast NNLO pQCD Calculations

fastNLO is a library that allows for fast NNLO pQCD calculations by interpolating parton distribution functions. This makes it possible to reuse the results of an expensive Monte Carlo integration for arbitrary a posteriori choices of the PDFs, the strong coupling constant, and the energy scales. This thesis implemented a new procedure for determining momentum fraction nodes for the interpolation in which new nodes are added dynamically as needed. This obsoletes one of the steps in the previous workflow in which the interpolation nodes were first determined in a so-called "warmup" run.
