// Main program for CSE 401 / CSE M 501 homework 3, part 2.

// Two additional classes must be defined: Parser, which must be
// a recursive-descent parser for the calculator language, and
// Scanner, which should contain a method that the parser can call
// each time it want to get the next token from the calculator input.

// We strongly suggest that you put these classes in separate files
// named Scanner.java and Parser.java in the same folder as this file.
// None of these files should contain package declarations - just leave
// everything in the default (unnamed) by omitting package from your code.

// The run() method in class Parser should cause the calculator to
// begin execution, reading and processing input until a quit command
// is entered.
