+   *
+   *    math.parser()

+   * Examples:
+   *
+   *     const parser = new math.parser()
+   *
+   *     // evaluate expressions
+   *     const a = parser.evaluate('sqrt(3^2 + 4^2)') // 5

+   *     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')                // 3.5
+   *     const f = parser.get('f')                // function
+   *     const g = f(3, 2)                        // 9
+   *     parser.set('h', 500)
