Detailed Description

This class provides the non-linear optimization of the peak parameters.

Given a vector of peak shapes, this class optimizes all peak shapes parameters using a non-linear optimization. For the non-linear optimization we use the Levenberg-Marquardt algorithm provided by the Eigen.
