[Issue-13] Add option to disable dismiss UI.

[devyml]

Introduction

We have no way of disabling the swipe down, tap on dimmer, or accessibility escape gesture which we use to dismiss the sheet. Some apps might require that the user not be able to dismiss the sheet without choosing a CTA or taking a specific action.

Purpose

• Introduce new option to disable dismiss.
• Fix Add option to disable dismiss UI #13

Scope

We have added a new property allowDismiss in appearance. If it is true then we can dismiss the bottom sheet else we are suspending the dismiss action

Discussion

BottomSheetViewController.swift had grown too large, so as part of this PR I moved the animator functionality out to a separate code file.

You kind of swapped Introduction and Purpose. Introduction is the more casual introduction of what the problem is or why we are bothering to make a change at all. Purpose is the stated goal of the PR. So I would do:

You also probably should use the Discussion section to talk about why you introduced a new file.

Looks great. Let's get this merged and release a new version.
