Please add multi modal widget

[genusistimelord]

this sounds like a decent change!

@genusistimelord please review PR #169. I think it is a better solution to support multiple overlays: it removes the show_modal boolean altogether and changes overlay into an Option. This way it allows maximum flexibility in choosing whether to display an overlay or not (by passing None). The PR is still partial (I updated only the functional code, not the comments / documentation), but would like to get your feedback on this possible approach before completing it.

Actually I think there is even a simpler solution: by removing the Option from overlay in PR #169, the user could simply show directly underlay (without calling modal) when the overlay should not be shown. This would actually be my preference, but I ask your opinion before implementing it. With this implementation, modal would always have the overlay visible when called.

If you do not like the two above implementations, then a new multimodal widget should be added accepting a Vec of overlays and an usize. If the usize corresponds to an element of the Vec of overlays, that overlay should be shown, otherwise no overlay should be shown. IMHO this is not needed though, as the above two implementations (in particular the second one) are simpler and allow maximum flexibility.

yeah just fix the clippy issue as it should be good to merge.

[genusistimelord]

Oh and add an example showing multiple modals in usage would be nice too.

Hi @genusistimelord I saw that you already merged PR #169 and fixed the clippy issue yourself. Sorry I did not answer before but yes I am adding a multiple modals example, just hold on and I am going to PR it. Before that I am also going to fix the modal's comments and documentation.

[genusistimelord]

ok thats fine. PR whenever your ready. I will close this since the last one fixed the problem.
