-====== C++ for Beginners ======
-This is a very short introduction into a couple of concepts of C++. It should enable a beginner without knowledge in C++ to properly use EEROS in an own simple application.
-===== Namespaces =====
-With namespaces you can group entities such as classes or enums under a choosen name. In this way the global scope can be split into subscopes with distinguished names. EEROS heavely uses namespaces.  \\
-In order to use declarations from these namespaces we can either import such a namespace or use the scope operator '::'. Let's look at an example.
-<code cpp>
-using namespace eeros::logger;
-int main(int argc, char **argv) {
-	StreamLogWriter w(std::cout);
-	Logger<LogWriter>::setDefaultWriter(&w);
-	Logger<LogWriter> log;
-	eeros::control::Constant<std::array<double,4>> c1;
-	using eeros::control::Gain;
-	Gain<> g1;
-</code>
-With 'using namespace eeros::logger' all the declarations in this namespace are made visible and can be directly used. \\
-The block 'Const' within the namespace 'eeros::control' is used with the aid of the scope operator.\\
-The block 'Gain' within the namespace 'eeros::control' is made available by 'using eeros::control::Gain;' and can be referred to further on without qualifying with the namespace.
