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