Added the basic Python files and the xml file to be parsed.
Moved the XML parsing code to a differnet module and imported this module in the main file
Changed the strings that are displayed on the buttons

Also called the parsing function in the new module and not from native code in this file
Added the preliminary drag-drop interface for all the buoys.
Renamed files to have a meaningful name.

* main.py : The present working copy of the final GUI
* module-drag-drop-.py : The main function/module that is being implemented in the main.py file
* module-*-graphics-view.py : Testing file. GUI can also be achieved using graphics view.
Figured out the button that has been moved and the string
that is there inside that button using the event source
function.
Added a function in the parseXML module.

* This function finds the appropriate tag that will be edited.
* This function now prints the name of the tag, the old value and the new value
all as floats, with two decimal points.

TODO: The new value has to be written to the xml file.
The new tree is written to a file called scene_2.xml.

* A lot of information in the robot tag is lost. Confirm with nevin whether this information needs to be retained.

* If info needs to be retained, then, figure out how to do that.
The left mouse button can also be used to move the elements.
Created a global filename, and referred to it everywhere
Added the latest XML.
Created a new python script that adds the lost robot tag information
to the modified XML file.
Added a bash script that will run the main and the fileWrite scripts in succession.

Fixed filenames.

input.xml => Input file
output.xml => Output file

The bash script after running the two python scripts, will also rename the
output.xml file to input.xml.
