-/*! \file
- 
-  \brief Class creaMessageManager and Macros for outputing messages in crea
-
-  There are 4 kinds of messages :
-  - Messages (normal messages)
-  - Debug messages (not compiled in release)
-  - Warnings 
-  - Errors
-  There are also "types" of messages which are strings which identify the nature of the message 
-  (for example : "Kernel" messages are generated by the core classes of the library, there can be a type of 
-  message for each type of Node, and so on...)
-  A type of message must be declared by registering it into the MessageManager. This is done by a line like :
-  crea::MessageManager::RegisterMessageType("Kernel","Messages generated by the core classes of the library",5);
-  where : 
-  -The first string is the type of the message (the category which will be used to generate a message of this type)
-  -The second string is help string
-  -The integer is the initial level for the messages of this type (see below).
-  
-  To generate a message of a known type then use one of the macros :
-  creaMessage, creaDebugMessage, creaWarning, creaError or their variants.
-
-  example :
-
-  creaMessage("Kernel",4,"problem with "<<GetName()<<creaendl);
-
-  will push the 3rd argument in std::cout if the message level of "Kernel" messages is greater or equal to 4.
-  which means that it generates a message of level 4 (0 : very important/always displayed ... 9 : deep debug message).
-
-  At run time, one is able to change the level of the messages displayed by using a command like :
-  
-  crea::MessageManager::SetMessageLevel("Kernel",5); 
-  
-  which tells the manager to display all Kernel messages of level up to 5.
-
-  Variants :
-
-  crea*Cont : continues a previous creaMessage on the same line (without rewriting the type and level)
-  crea*Inc / Dec : displays the message and then increments/decrement the messages tabulation
