Cat_plot converts numeric predictor variable to categorical without warning

[shan-e-s]

Using 'cat_plot' with a continuous predictor variable converts the predictor into a character variable. This means x axis labels can be very messy as they overlap and its difficult (or maybe impossible) to set breaks so these dont overlap. I had this issue but i eventually realised i should have been using 'interact_plot' instead of 'cat_plot'.

If 'cat_plot' tested for the variables being numeric before plotting and issued a warning that 'interact_plot' is better suited to plotting these variables it might save other users making this same mistake.

Thanks for a great package!
