ndns

The code should be updated to more closely follow ndn-cxx code style:

• limit lines <= 100 columns
• ! private member variables MUST have m_ prefix
• avoid tabs
• avoid C comments (except doxygen blocks).
• correct spaces around "<<" (should be), ++ (should not be)
• avoid trailing whitespace and dangling newline at the end of the file
• (not really ndn-cxx, but we should do it)
• new line before else and else if (should be)

• methods declaration and definition should be (name and return type always separated)

  const Response& 
  getResponse() const;
  

  and

  const Response& 
  getResponse() const
  {
  }
  

• there should not be space between type and & and * and there should be space before variable. Like Name& name or const char* string

• ifndef guards should have correct names that follow file path and name. For example, for name-dig.hpp in src/app, the guard name should be NDNS_APP_NAME_DIG_HPP

• add new line between license boilerplate and guard or first include

• indentation should be corrected. There are several places where it is used inconsistently

Other related things:

• use correct license boilerplate in files
• remove automatically generated comments (e.g., "TODO Auto-generated destructor stub")
• const& should be used for passing complex types, such as std::string:
