Warning about using deprecated `father` argument to igraph::dfs()

[MatthewHeun]

I'm receiving the following warning in some of my code:

The `father` argument of `dfs()` is deprecated as of igraph 2.2.0. 
ℹ Please use the `parent` argument instead. 
ℹ The deprecated feature was likely used in the dm package.

I hope this helps.
