Param to constructor

[Lecrapouille]

Make it works (missing : m_arg1(arg1) + generate value for unit tests

• update Simple example

'[header] struct Arg1 { int foo; };
'[header] struct Arg2 { int bar; };
'[param] Arg1 arg1
'[param] Arg2 arg2
'[init] m_arg1 = arg1;
'[init] m_arg2 = arg2;

Generating

    SimpleController(Arg1 arg1, Arg2 arg2)
        : StateMachine(SimpleControllerStates::CONSTRUCTOR)
    {
        m_arg1 = arg1;
        m_arg2 = arg2;

but desired:

    SimpleController(Arg1 arg1, Arg2 arg2)
        : StateMachine(SimpleControllerStates::CONSTRUCTOR),
          m_arg1(arg1), m_arg2(arg2)
    {
