[Javacavemaps-developers] Added a SurveyXMLTest to the original source

[X. G. R. <ark...@gm...>]

I just added a first draw of a class that manipulates XML data for the
survey.
It created the XML Document, saves it to a physicial file and loads the data
from the file.
It's not implemented as a test case, just a plain class.
I first wanted to know opinions on if that is useful enough, and if it is
really necesary to Add a JUnit test case(or any other kind).

Check the main method in
net.sourceforge.javacavemaps.casetest.arkalain.case1.SurveyXMLFile.java. To
test it just execute the class
as a java application.

Thank you,
