   File Name:          15.7.2.js
   ECMA Section:       15.7.2 The Number Constructor
   15.7.2.1
   15.7.2.2

   Description:        15.7.2 When Number is called as part of a new
   expression, it is a constructor:  it initializes
   the newly created object.

   15.7.2.1 The [[Prototype]] property of the newly
   constructed object is set to othe original Number
   prototype object, the one that is the initial value
   of Number.prototype(0).  The [[Class]] property is
   set to "Number".  The [[Value]] property of the
   newly constructed object is set to ToNumber(value)

   15.7.2.2 new Number().  same as in 15.7.2.1, except
   the [[Value]] property is set to +0.

   need to add more test cases.  see the gTestcases for
   TypeConversion ToNumber.
