/*! \brief parser class for INI-style configuration files
    \ingroup jkip

   You may use this class to parse an INI file (\c readFile(<filename>)) and
   then access its contents (\c getAs*, \c jkinifile::getAsParsed*). It is
   also possible to change the contents and to subsequently save the INI file to the
   disk (\c writeFile(<filename>). In the lather case all comments in the
   prevoiusly loaded INI file will be lost.


   This parser supports a specialised INI format which interprets every right hand side as
   a mathematical expression. So you can do simple calculations. It is also possible to use
   all previously defined variables in an expression. In contrast to jkiniparser (v1.0) you
   will have to enclose all string data in quotation marks \c "...". If an unparsable expression
   is encountered the according value is taken to be a string.


   Also the names of the properties are treated in a special way. Basically there are two possibilities
   to mark the current group and property names:

   <b>possibility 1:</b>
   \code
   [group1]
   data1="hallo"
   data2=123

   [group2]
   data1=true
   \endcode
   Here all properties after a group \c [groupname] belong to this group

   <b>possibility 2:</b>
   \code
   group1.data1="hallo"
   group1.data2=123
   group2.data1=true
   \endcode
   Here the grou name is the part of the string befor the first dot/period.


   You may also use any combination of the two possibilities, so also this ini file is the same as the above two:
   \code
   group1.data1="hallo"
   group1.data2=123

   [group2]
   data1=true
   \endcode


   \section jkip2_example Example of Usage

    Here is a simple example of the usage:
    \code
    jkINIParser2 ini;
    try {
       ini.readFile("test.ini"); // read in an INI file
       cout<<endl<<endl<<"printing all contents in the file ..."<<endl;
       ini.print();

       // read some data
       cout<<"gruppe1.intdata = "<<ini.getAsInt("gruppe1.intdata", -10)<<endl;
       cout<<"gruppe1.doubledata1 = "<<ini.getAsDouble("gruppe1.doubledata1", -10.00125)<<endl;
       cout<<"gruppe1.stringdata = "<<ini.getAsString("gruppe1.stringdata")<<endl;

       // change the current root and set there some data
       ini.enterGroup("gruppe1");
       ini.set("intdata", -100.0);
       ini.leaveGroup();

       cout<<"printing all group names on the top level ..."<<endl;
       if (ini.getGroupCount()>0) {
         for (unsigned long i=0; i<ini.getGroupCount(); i++) {
           cout<<ini.getGroupName(i)<<endl;;
         }
       }
       ini.set("gruppe2.data", 15.678);

       cout<<endl<<endl<<"printing all contents in the file ..."<<endl;
       ini.print();


       ini.writeFile("test_out.ini"); // write the changed INI file to disk

       // trying to re-read the currently
       ini.readFile("test_out.ini");
       cout<<endl<<endl<<"printing all contents in the file ..."<<endl;
       ini.print();

       // read another, more complex file
       ini.readFile("diffusion3.ini");
       cout<<endl<<endl<<"printing all contents in the file ..."<<endl;
       ini.print();

    } catch (std::exception& e) { // error handling
       cout<<"error:   "<<e.what()<<endl;
    }
    \endcode

    <b>example of an INI file:</b>
    \code
     [Group]
     param1 = value_part1\
              value_part2  # comment
     param2 = value
     # comment
    \endcode


    \section jkip_error Error Handling
    This class implements two modes of error handling that may be controlled by the global variable
    jkiniparser_exception_function. By default this variable is \c NULL and the jkiniparser
    throws jkipError exceptions on any error condition. If this behaviour is not wished for, because
    maybe your programming environment does not support std::exception (this is one of the problems
    when writing C++ code for Matlab MEX-files), you can let jkiniparser_exception_function point to
    an error handling function that should also stop the program due to the error and output the
    error to the user. a simple implementation could look like this:

    \code
    void errorHandler(std::string errorMessage) {
        std::cout<<"there was an error while parsing an ini file:\n    "<<errorMessage<<std::endl;
        abort();
    }
    \endcode



    \section jkip_ebnf EBNF Rough Grammar of Ini Files
    <pre> ini_file           -> { ini_file_element }</pre>
    <pre> ini_file_element   ->  EndOfFile

    Every primary may be broken over several lines if there is a backslash '\\'
    in front of every line end marker '\\n'. This feature is activated only if
    jkiniparser::allowMultiLines is set to true (standard is false).

    The <code>!include filepath\filename.ini</code> statement loads the specified ini file at the specified
    position and parses it before going on with the  current ini file.

    Comments start with a \c # and last until the end of the current line.
