Detailed Description

These data types have been added to make working with input data more regular. Referring to the input rendering system Type Manipulation and Column Name re-mapping. This requires that data types support boost::lexical_cast<T>. We would also like to have numeric types that have some notion of their scale. Another issue is that date strings come in a number of formats and boost::gregorian::date doesn't support boost::lexical_cast<T>.

These data types have been added to provide these features.

Each of these data types associated null0 and a rendering function as(). These are implemented using a null1(), a ys() and an xs(). You will also need to add the Renderer to the eepgwde::detail::Typing::types0() map.

A default constructor is needed for these types.

These classes need a default constructor and stream << and >> operators to use boost::lexical_cast: this is the templated method of for implementing as().
