PR Summary

Introduces a new MarinerGuidance.java file implementing a control system with guidance algorithms for marine navigation using PD (Proportional-Derivative) control.

• Fixed control coefficients (-0.5 position, 2.0 derivative) in someControlLaw() method may need tuning for different marine conditions
• Missing boundary checks in getRawDerivative() could lead to array index out of bounds exceptions
• Test dataset in main method lacks comprehensive error handling
• Control system implementation assumes constant sampling rate without handling variable time steps

logic: No bounds checking on array access. Could throw ArrayIndexOutOfBoundsException if n >= radius.length

Suggested change

	public static double getRawDerivative(double[] radius, int n) {
	if (n == 0) return 0.0;
	return radius[n] - radius[n - 1];
	public static double getRawDerivative(double[] radius, int n) {
	if (n == 0) return 0.0;
	if (n >= radius.length) throw new IllegalArgumentException("Index n must be less than array length");
	return radius[n] - radius[n - 1];
