-/// static class template for the string representation of values
-/**
- <b>value</b> serves as a base to for the representation
- of atomic types and classes as strings.
-
- The function <tt>toString</tt> is defined for all atomic (built in) types
- like <tt>int, double etc.</tt>. For types other than atomic ones namely
- classes the function template <tt>toString</tt> calls a member function
- <tt>as_string</tt> on the class-type passed to the template.
-
- Thereby we can implement a general string representation for template classes
- which is independent of the template parameter being an atomic or a class type.
- For every object, including atomic the string converter function toString can
- be called, provides new classes implement a memberfunction <tt>as_string</tt>
