+# This module finds if wxWindows is installed and determines where the
+# include files and libraries are. It also determines what the name of
+# the library is. This code sets the following variables:
+#
+#  WXWIDGETS_FOUND =     wxWidgets was found
+#  WXWIDGETS_ROOT_DIR =  base wxWidgets directory
+#  WXWIDGETS_LINK_DIRECTORIES = link directories, useful for rpath on Unix

+#  WXWIDGETS_CXX_FLAGS        = compiler flags for building wxWindows

+#  WXWIDGETS_INCLUDE_DIR    = all include path of wxWindows
+#  WXWIDGETS_DEFINITIONS  = all flags of wxWindows
+#
+#  WXWIDGETS_RELEASE_LIBRARIES       = release wxWindows libraries (Win32 only)
+#  WXWIDGETS_DEBUG_LIBRARIES       = debug wxWindows libraries (Win32 only)
+#  WXWIDGETS_COMMON_LIBRARIES  = libraries common to Release and Debug (Win32 only)
+
+# NOTE: This module REQUIRES that an environment variable named WXWIN
+# be set to the base wxWidgets installation directory.
+# Under Unix, you must also set and environment variable named WXWINCFG
+# to the name of the active build subdirectory (eg buildgtk).  As an alternative
+# to the WXWINCFG environment variable, you can set a sym link in the wxWidgets
+# root directory called wx-config which points to the active build subdirectory.
+#

+  /** A magic class which can store any type of data which 
+   * is allowed by the template template parameter TypeTrait.
+   *
+   * The only requirement on TypeTrait<T> is to have the member :
+   *    static const bool value;
+   * which is true iff the type T is an allowed type 
+   * 
+   * TypeTraits compliant objects are usually template structs 
+   * for which the initialisation of value is set to false by default 
+   * and set to true for the allowed types (template specialisation)
+   * Example :
+   *   template <typename T> struct mytypes { static const bool value; };
+   *   template <typename T> const bool mytypes<T>::value = false;
+   *   template <> const bool mytypes<int>::value = true;
+   *   template <> const bool mytypes<float>::value = true; 
+   * etc.
+   * You can use any boost type_trait, like is_pointer, is_floating_point, etc.
+   *
+   * The class any is a generalisation of the boost::any class 
+   * (see http://www.boost.org/doc/html/any.html).
+   * The boost::any class itself is reproduced by any<thing>,
+   * where thing is a TypeTrait whose value is true for all types.

+  There are also "types" of messages which are strings which identify the nature of the message 
+  (for example : "Core" messages are generated by the core classes of the librairy, 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 :
+  bbtk::MessageManager::RegisterMessageType("Core","Messages generated by the core classes of the library",5);
+  where : 
+  -The first string is the type of the message (the keyword 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 :
+  bbtkMessage, bbtkDebugMessage, bbtkWarning, bbtkError or their variants.
+
+  example :
+
+  bbtkMessage("Core",4,"problem with "<<GetName()<<bbtkendl);
+
+  will push the 3rd argument in std::cout if the message level of "Core" 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 :
+  
+  bbtk::MessageManager::SetMessageLevel("Core",5); 
+  
+  which tells the manager to display all Core messages of level up to 5.
+
+  Variants :
+
+  bbtk*Cont : continues a previous bbtkMessage on the same line (without rewriting the type and level)
+  bbtk*Inc / Dec : displays the message and then increments/decrement the messages tabulation

+/**
+ ****************************************************************************
+ * <P> XML.c - implementation file for basic XML parser written in ANSI C++
+ * for portability. It works by using recursion and a node tree for breaking
+ * down the elements of an XML document.  </P>
+ *
+ * @version     V2.23
+ * @author      Frank Vanden Berghen
+ *
+ * NOTE:
+ *
+ *   If you add "#define STRICT_PARSING", on the first line of this file
+ *   the parser will see the following XML-stream:
+ *      <a><b>some text</b><b>other text    </a>
+ *   as an error. Otherwise, this tring will be equivalent to:
+ *      <a><b>some text</b><b>other text</b></a>
+ *
+ * NOTE:
+ *
+ *   If you add "#define APPROXIMATE_PARSING" on the first line of this file
+ *   the parser will see the following XML-stream:
+ *     <data name="n1">
+ *     <data name="n2">
+ *     <data name="n3" />
+ *   as equivalent to the following XML-stream:
+ *     <data name="n1" />
+ *     <data name="n2" />
+ *     <data name="n3" />
+ *   This can be useful for badly-formed XML-streams but prevent the use
+ *   of the following XML-stream (problem is: tags at contiguous levels
+ *   have the same names):
+ *     <data name="n1">
+ *        <data name="n2">
+ *            <data name="n3" />
+ *        </data>
+ *     </data>
+ *
+ * NOTE:
+ *
+ *   If you add "#define _XMLPARSER_NO_MESSAGEBOX_" on the first line of this file
+ *   the "openFileHelper" function will always display error messages inside the
+ *   console instead of inside a message-box-window. Message-box-windows are
+ *   available on windows 9x/NT/2000/XP/Vista only.
