      /// DynamicAny allows to store data of different types and to convert between these types transparently.
      /// DynamicAny puts forth the best effort to provide intuitive and reasonable conversion semantics and prevent 
      /// unexpected data loss, particularly when performing narrowing or signedness conversions of numeric data types.
      ///
      /// An attempt to convert or extract from a non-initialized (empty) DynamicAny variable shall result
      /// in an exception being thrown.
      ///
      /// Loss of signedness is not allowed for numeric values. This means that if an attempt is made to convert 
      /// the internal value which is a negative signed integer to an unsigned integer type storage, a RangeException is thrown. 
      /// Overflow is not allowed, so if the internal value is a larger number than the target numeric type size can accomodate, 
      /// a RangeException is thrown.
      ///
      /// Precision loss, such as in conversion from floating-point types to integers or from double to float on platforms
      /// where they differ in size (provided internal actual value fits in float min/max range), is allowed.
      /// 
      /// String truncation is allowed -- it is possible to convert between string and character when string length is 
      /// greater than 1. An empty string gets converted to the char '\0', a non-empty string is truncated to the first character. 
      ///
      /// Boolean conversion is performed as follows:
      ///
      /// A string value "false" (not case sensitive), "0" or "" (empty string) can be converted to a boolean value false,
      /// any other string not being false by the above criteria evaluates to true (e.g: "hi" -> true).
      /// Integer 0 values are false, everything else is true.
      /// Floating point values equal to the minimal FP representation on a given platform are false, everything else is true.
      ///
      /// Arithmetic operations with POD types as well as between DynamicAny's are supported, subject to following
      /// limitations:
      /// 
      ///   - for std::string and const char* values, only '+' and '+=' operations are supported
      /// 
      ///   - for integral and floating point numeric values, following operations are supported:
      ///     '+', '+=', '-', '-=', '*', '*=' , '/' and '/=' 
      ///
      ///   - for integral values, following operations are supported:
      ///           prefix and postfix increment (++) and decement (--)
      /// 
      ///   - for all other types, InvalidArgumentException is thrown upon attempt of an arithmetic operation
