About configuration XML files.

Now we merged ROME and ARGUS.
So I expect that users often have several configuration files for one project.

But I realized many people don't know that they can specify configuration file.

So I propose following scheme.

* When a program starts, it searches all XML files located in current directory which has <Configuration> tag at the top.
* If it does not find any XML file, it asks user to generate new one.
   * ask configuration type [R/A/M/N]
   * ask filename. Default is romeConfig.xml
* If it find only one XML file, it reads the XML file.
* If it find several XML files, it asks user which file should be used with a prompt like,
     Which configuration file do you use ?
      [1] filename1.xml
      [2] romeConfig.xml
      [3] filename2.xml
      [q] quit program
* When user starts program with option -c, it asks creates new configuration anyway.
* When user starts program with option -i, it uses specified file.
