 INtegration of ODE's using RUNGE-KUTTA-formula 4

 This function implements the vectorized RUNGE-KUTTA-Integrator 4.

 Syntax:  [Timevec, Result] = intrk4(SIM_F, Times, XINIT, Options, Control, P1-Px)

 Input parameters:
    SIM_F     - function to simulate
    Times     - vector containing TStart (start time - optional) and TEnd (end time)
    XINIT     - initial values for the simulation of the individuals
                every row contains the initial values for 1 individual
    Options   - vector containing [ERRMAX: max. rel. error, STEPMIN: min. stepsize, STEPMAX: max. stepsize, ...
                                   (optional) NCONTR: number of control variables]
    Control   - control vector/matrix, every row is one control vector
                format:   1. ControlVariable  2. ControlVariable ...  NCONTR. ControlVariable
                         --------------------------------------------------------------------
                  Ind1: | 1:ControlSteps      1:ControlSteps     ...  1:ControlSteps
                  Ind2: | 1:ControlSteps      1:ControlSteps     ...  1:ControlSteps
    P1 - Px   - (optional) parameters passed through to simulation function

 Output parameters:
    Timesim   - vector containing time of simulation steps
    Result    - results, state vectors
                format:   1. ControlVariable  2. ControlVariable ...  NCONTR. ControlVariable
                         --------------------------------------------------------------------
                  Ind1: | 1:ControlSteps      1:ControlSteps     ...  1:ControlSteps
