// Functions Implementing this interface should check out 
// System.Convert. Most of these methods are implemented 
// there for all these data types.
//
// System.Convert has ToType helper method for the object 
// ToType (Type conversionType, IFormatProvider provider)
// method. In most cases you can specify your ToType function
// as calling 
//
// public Type value; // value of this data type
// public object ToType(Type conversionType, IFormatProvider provider) {
//    Convert.ToType (value, conversionType, provider);
// } 
// 
// Which is just a wrapper for your ToType methods.
//
// See http://lists.ximian.com/archives/public/mono-list/2001-July/000525.html
