Conflict between variable name and field name

[eaurele]

df <- data.frame(V1 = c("bar", "bar/foo"), foo = 1:2, stringsAsFactors = FALSE)
as.Node(df, pathName = "V1")

causes:
Error in mynode$level : $ operator is invalid for atomic vectors
probably because of variable foo named like field foo

That is indeed not possible, as both name and fields are stored in the same environment. I agree that the error message could be a bit more expressive. Also, I had the idea to make this a bit less likely to happen with #66. But I'm still undecided.

Will try to improve the error message.

A warning has been added if name conflict occurs.
