/**
* Levenberg-Marquardt optimization.
*
* An optimization method that iteratively searches for the optimal function parameters
* that best describe the dataset. The 'input' is the function being optimized, a set of real data
* (calculated with independent variables, but with an unknown set of parameters), a set of
* independent variables, and variables for adjusting the algorithm, described in the documentation for the LMInput class.
* The function returns number of completed iterations, the number of evaluations of the input function during execution,
* chi squared value on final parameters, final lambda parameter used to calculate the offset, final parameters
* and type of convergence in the 'output'.
*
* @receiver the `input`.
* @return the 'output'.
