/*
* toString()
*
* The student object will be put into string representation. Student info will be
* ordered ID, name, address, phone number, and GPA. Each piece of information will
* be on its own line. GPA will not have a newline following it and the precision
* of the GPA will be rounded to two decimal places. For example,
*
* 123456789
* Ben Thompson
* 17 Russell St, Provo, UT 84606
* 555-555-5555
* 3.12
*
* Returns a string representation of the student object There is no trailing new line.
