Implemented a subclass StepVector of MathNet.Numerics.LinearAlgebra.Double.DenseVector with mapping capabilities for particles, nodes and property names (which was previously done by LagrangianGradient directly).
Needs a modified version of MathNet.Numerics with vector API of Broyden.
StepVector shall be converted as late as possible in solver to particle time steps.
