Use Epsilon in CreateInputsCrit

I have some issues with the use of epsilon in CreateInputsCrit.

The RDocumentation says: (optional) [numeric (atomic or list)] small value to add to all observations and simulations when "log" or "inv" transformations are used [same unit as Obs]. See details

However when we go to the details the epsilon value have an effect on every transformation except for "boxcox".

It's a bit contradictory...

In addition, only "log" and "inv" transformations are checked for the warning "zeroes detected in Obs: the corresponding time-steps will be excluded by the 'ErrorCrit*' functions as the epsilon argument was set to NULL". We should expand this warning to any power function < 0 (ex: transfo = -0.5).
