main class code added for miniJava
can have only one statement in main method
Sum Difference program description added
added gitignore file
added Sum Difference class
can have multiple statements, just have to add another pair of curly brackets
initialise method added
initialize method added successfully without any parsing errors for SumDiff object
full invoke where I initialise, return object and call the method that will run the main calc
Added SumDiff class to MainClass.java file, SumDiff parses correctly for this reason
Seperate java files will not work
Sum Difference program working properly, parsing is fully successful as well
