Here is the first public release of the subdiv script :)
In fact this is only a half of the script. It works correctly with ordinary and polar vertices only. But it still has some problems with extraordinary vertices in some cases. I'll finish the second half of the script in nearest future. There will be two methods of subdivision: fast and accurate. Here is an implementation of the fast mode only.

Usage:
Select one solid or group of solids. Run script.

P.S. Would like to thank everybody for support. Thank you!
The idea about a donate button is good. Maybe sometime, but not now :)
