/** Class for inserting binary regions types into Pantheios diagnostic
 *   logging statements.
 *
 * \ingroup group__application_layer_interface__inserters
 *
 * This class formats a binary region into a string, thereby enabling it to
 * be inserted into a logging statement. Consider the following statement:
 * \code
  int         ar[2] = { 0x00112233, 0x44556677 };
  char        s[]   = "abc";
  std::string str("def");

  pantheios::log(pantheios::notice, "s=", s, ", b64=", pantheios::b64(ar, sizeof(ar)), ", str=", str);
 * \endcode
 *
 * This will produce the output:
\htmlonly
<pre>
   <b>s=abc, b64=0011223344556677, str=def</b>
</pre>
\endhtmlonly
 *
 * The bytes can be grouped and these groups separated. Consider the
 * following statement:
 * \code
  int         ar[2] = { 0x00112233, 0x44556677 };
  char        s[]   = "abc";
  std::string str("def");

  pantheios::log(pantheios::notice, "s=", s, ", b64=", pantheios::b64(ar, sizeof(ar), 2, "-"), ", str=", str);
 * \endcode
 *
 * This will produce the output:
 * \htmlonly
<pre>
   <b>s=abc, b64=2233-0011-6677-4455, str=def</b>
</pre>
\endhtmlonly
 *
 * The output can be split into lines. Consider the following statement:
 * \code
  int         ar[2] = { 0x00112233, 0x44556677 };
  char        s[]   = "abc";
  std::string str("def");

  pantheios::log(pantheios::notice, "s=", s, ", b64=", pantheios::b64(ar, sizeof(ar), 2, "-", 3, "\n\t"), ", str=", str);
 * \endcode
 *
 * This will produce the output:
\htmlonly
<pre>
  <b>s=abc, b64=2233-0011-6677
          4455, str=def</b>
</pre>
\endhtmlonly
