Rev 0.5 made particle count equation with radius so radius increases with cloud volume
Rev 0.6 added poll function to operator, fixing crash with no selected objects
Rev 0.7 added particles option and Type of Cloud wanted selector
+Rev 0.8 fixed particles by commenting out add cloud texture force field
+Rev 0.9 Added smoothing and explosion material
+Rev 1.0 Added ability to convert object with particle system to cloud and auto resizing of bound box
