Why there are "each" versions of functions?

[mitar]

I think it could be simplified so that one could do:

type PageData struct {
	Link    string   `pagser:"a->attr(href)"`
	Links   []string `pagser:"a->attr(href)"`
}

The package could inspect the type associated with the tag and if it is slice, automatically assume "each" behavior. In general I think all functions should be returning slices, which then optionally are converted to an individual value (by default the first one, but you could set using ->Eq some other index).

It like a good idea.
