/**
* This macro can be used to :
* - declare a type as a Qt meta type
* - and register it (through a static instance) at the launch of SciQlop, so it can be passed in
* Qt signals/slots
*
* It can be used both in .h or in .cpp files
*
* @param NAME name of the instance under which the type will be registered (in uppercase)
* @param TYPE type to register
*
* Example:
* ~~~cpp
* // The following macro :
* // - declares std::shared_ptr<Variable> as a Qt meta type
* // - registers it through an instance named VAR_SHARED_PTR
* SCIQLOP_REGISTER_META_TYPE(VAR_SHARED_PTR, std::shared_ptr<Variable>)
*
* // The following macro :
* // - declares a raw pointer of Variable as a Qt meta type
* // - registers it through an instance named VAR_RAW_PTR
* SCIQLOP_REGISTER_META_TYPE(VAR_RAW_PTR, Variable*)
* ~~~
