-	/// <summary>A MoneyBag defers exchange rate conversions.</summary>
-	/// <remarks>For example adding 
-	/// 12 Swiss Francs to 14 US Dollars is represented as a bag 
-	/// containing the two Monies 12 CHF and 14 USD. Adding another
-	/// 10 Swiss francs gives a bag with 22 CHF and 14 USD. Due to 
-	/// the deferred exchange rate conversion we can later value a 
-	/// MoneyBag with different exchange rates.
-	///
-	/// A MoneyBag is represented as a list of Monies and provides 
-	/// different constructors to create a MoneyBag.</remarks>
