/** Class for inserting Boolean types into Pantheios diagnostic logging
* statements.
*
* \ingroup group__application_layer_interface__inserters
*
* Consider the following statement:
*
* \code
char s[] = "abc";
std::string str("def");
bool b = false;
pantheios::log(pantheios::notice, "s=", s, ", b=", pantheios::boolean(b), ", str=", str);
* \endcode
*
* This will produce the output:
*
* &nbsp;&nbsp;&nbsp;&nbsp;<b>s=abc, b=false, str=def</b>
*
* \note The class provides the static method set_value_strings() for
* assigning user-defined strings to represent true and false values.
