INSTRUCTIONS:
Make changes as follows:
Add a regular expression-based check to ensure that the input to setNIIN() and the full argument constructors for all Parts (which is every Class in the project) is correct.
Remember, a NIIN must be of the form NNNN-NN-NNN-NNNN, where each N is a digit ( e.g. a 0,1,2,3,4,5,6,7,8, or 9)
Add a regular expression-based check to ensure that the input to setNcage() and the full argument constructors for all Parts (which is every Class in the project) is correct.
Remember, a NCAGE must be of the form NNNNN, where each N is a number or capital letter
