     * Create a parser. The function creates a new `math.Parser` object.
     *
     * Syntax:
     *
     *    math.parser()
     *
     * Examples:
     *
     *     const parser = new math.parser()
     *
     *     // evaluate expressions
     *     const a = parser.evaluate('sqrt(3^2 + 4^2)') // 5
     *     const b = parser.evaluate('sqrt(-4)')        // 2i
     *     const c = parser.evaluate('2 inch in cm')    // 5.08 cm
     *     const d = parser.evaluate('cos(45 deg)')     // 0.7071067811865476
     *
     *     // define variables and functions
     *     parser.evaluate('x = 7 / 2')             // 3.5
     *     parser.evaluate('x + 3')                 // 6.5
     *     parser.evaluate('f(x, y) = x^y')         // f(x, y)
     *     parser.evaluate('f(2, 3)')               // 8
     *
     *     // get and set variables and functions
     *     const x = parser.get('x')                // 7
     *     const f = parser.get('f')                // function
     *     const g = f(3, 2)                        // 9
     *     parser.set('h', 500)
     *     const i = parser.evaluate('h / 2')       // 250
     *     parser.set('hello', function (name) {
     *       return 'hello, ' + name + '!'
     *     })
     *     parser.evaluate('hello("user")')         // "hello, user!"
