Fuse ugen

Years ago (gasp... 5 !) I wrote a UGen called Fuse that blocked NaN, inf and other nasty blow ups.  It protected the server; useful for putting on individual channels.

unfortunately I lost the source code and the build so I need to write it again.

does anybody have anything similar already ?  otherwise I'll have a go at it.  its not a complicated idea.

I've been playing with lots of the josh, mcld, blackrain, bhob ugens lately.  awesome stuff !
