Mike Clark 212ff0bc70 moving epsilon outside softplus 
I think you intended this to be outside the softplus. The reason is that it should be applied just before the log to avoid `log(0)=inf`.e.g.

- `log(softplus(-1000+1e-5))=log(0)=inf`. 
- `log(softplus(-1000)+1e-5)=log(1e-5)!=inf`. 

Also this fixes a NaN I had.
