	-- Lets say we have a serialized class called Save --

	[System.Serializable]
	public class Save
	{

	public List<string> TestStrings = new List<string>();

	Save save = new Save();
	save.testInt = 5;
	save.TestStrings.Add("Hello");

	SaveUtility.Save(save, "testPath");

	-- For loading this class we would do the following --> --

	Save save = SaveUtility.Load<Save, string>("testPath");

	Important : Since save operation uses PlayerPrefs and does not contain any encrypting. Dont save&load any confidential data using this class.
