 Let's take a closer look at how to use `geom_edge_label()`.  
 In most cases you hopefully won't have to worry much about this geom, since the defaults should produce satisfying results.  
-But if you do want to customize anything, it might get a bit tricky. Since splits of continuous variables contain intervals we want to be able to plot inequality signs.

Using Unicode to do so, proved problematic among other things with some pdf engines. Therefore these signs are added as parsable text.  
 However, this opens the door to some other potential problems. To ensure correct behaviour as per default `geom_edge_label()` parses only these signs. Therefore the additional argument `parse_all` has been added which allows to parse the whole label if set to `TRUE`.
