Tutorial documentation doesn't parse `///` and `\`

Original report (archived issue) by Carlos Agüero (Bitbucket: caguero, GitHub: caguero).

• ////////////////////////////////////////////////// inside a code block is ignored.
• \brief is extracted from the code block and rendered before the code snippet. Probably because is a Doxygen reserved word.

Here's the result of generating documentation for this tutorial:

#!python

 # Test

 Here's a code snippet:

 ```{.cpp}
 //////////////////////////////////////////////////
 /// \brief Provide an "echo" service.
 bool srvEcho(const ignition::msgs::StringMsg &_req,
   ignition::msgs::StringMsg &_rep)
 {
   // Set the response's content.
   _rep.set_data(_req.data());

   // The response succeed.
   return true;
 }

And this is how it looks:

Here's the result of generating documentation for this tutorial:

!python

Test

The same tutorial without the separator and doxygen tag:

 bool srvEcho(const ignition::msgs::StringMsg &_req,
   ignition::msgs::StringMsg &_rep)
 {
   // Set the response's content.
   _rep.set_data(_req.data());

   // The response succeed.
   return true;
 }

@caguero this seems like an issue with doxygen and not something gz-cmake can fix. Is it okay if we close this issue?
