Updates the getStringValue method of the VariableNode class so that it correctly handles multidimensional arrays. The default formatting of multidimensional arrays is to have the size of the first array written in the last set of brackets eg.int[][5]. This changes it so that the returned value has the size of the first array written in the first set of brackets eg.int[5][]. This can parse multidimensional arrays of any size.
