Incorrect documentation for in-place qraddcol! #14
Description
While testing out the package, I noticed that some code provided in the documentation, produces errors.
In the section on in-place operations,
qraddcol!(A,R,a,current_R_size)
will throw an error, as it expects 5 more AbstractVector{T}'s.
It is also unclear to me at this time if they serve a purpose other than memory pre-allocation.
