/*****
Function to open up a customised window for loading a URL or specific text by Ben.

TO USE:

You can call the function using various arguments

1) Load URL;

e.g.  infoWindow('foo.html','foowindow',400,200,'','','','topleft','')

will load foo.html into a 400*200 pixel window that is positioned at the top left of the screen

2) Load specific html content

e.g. infoWindow('','foowindow',450,300,'/images/bgimg.gif','My Window','<p>Any html</p>','','/styles/mystyle.css')

will open a 450*300 pixel window in the centre of the screen (default behaviour) containing the specified html content
with the specified background image and window title with the specified style-sheet applied.
