Definition of ValidX #80

First of all, thank you for this great package! It really helps me a lot during my PhD.

Second, I have a question concerning the output value "valdix". In the current package version (1.2.1) in function gsynth, it defines the value as follows: "a logic value indicating if multicollinearity exists."

In package version 1.0.6 in function interFE it defines the value as follows: "a bool value specifying whether there are valid covariates"

So, what does it mean now? I always get the value 1 and I am a bit confused. Maybe you could update the manual regarding a definition of the values. Thank you in advance!
