// We use this class to prevent the accidental returning of a boxed value type to a caller
// If we store a boxed value type in a private field, and return it to the caller through a public
// property or method, the call can potentially change its value. The GetSafeObject method does two things
// 1) If the value is a primitive, we know that it will implement IConvertible. IConvertible.ToType will
// copy a boxed primitive
// 2) In the case of a boxed non-primitive value type, or simply a reference type, we call
// RuntimeHelpers.GetObjectValue. This returns reference types right back to the caller, but if passed
// a boxed non-primitive value type, it will return a boxed copy. We cannot use GetObjectValue for primitives
// because its implementation does not copy boxed primitives.
