review usage of seealso tag #257
Description
The use of the roxygen tag @seealso is not all the way great yet. We need to do a couple of things. Firstly I don't think we need to link to the main recipes functions such as recipes(), bake(), prep()`.
the other part is that we need to make sure that we do is to link between similar functions in this package. Most of them are named similarly. There are also some functions like step_pca() and step_discretize() in recipes that we should link to, done using recipes::step_pca() syntax
