Function to evaluate plots (MATLAB® Grader)

This is a function created for the MATLAB®-Grader Course "Einführung in die Programmierung" ("Introduction to Programming") for Students of Bio-/Chemical Engineering at TU Dortmund. However this function can be used to determine if a Line (Object created by plot function) is in the current plot. This function uses the gca object, so no additional variable needs to be a assigned by the student (Or in your code)

Usage:
mg_isCurveInPlot('Patameter1', 'value1', Patameter2', 'value2', ...);

Return:
logical 1: A line in the current Graph fits the requirements.
logical 0: No line in the current Graph fits the requirements.

Notes:
You can check any property of the line object.
Most useful ones are:
XData, YData, ZData: 1 x n - vector
LineStyle: Char Array
LineWidth: Scalar
Color: Color-Vector

Look at the line object to get more information.
