Definition of ValidX

[Irazall]

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!
