Push notifications to your visitors with `BToast` and `BToaster`. These are lightweight components which are generally easily customizable for generating alert messages

Toasts are lightweight notifications designed to mimic the push notifications that have been popularized by mobile and desktop operating systems. Toasts are intended to be small interruptions to your visitors or users, and therefore should contain minimal, to-the-point, non-interactive content. Please refer to the Accessibility tips section below for important usage information

There are two acceptable options for the `show` function. The first set of options are a `string` followed by an `object`. The string corresponds to the body of the `Toast`. If only the string is passed, a simple `Toast` is made, and by default it is made at the `top-right` and it will expire in `5000` ms. You can pass in an optional `object` for the second parameter where you have a list of options, such as `pos`, `value`, `variant`, etc. Many of the values correspond to props for the `BToast` component. However, some props are taken out as they are reserved

show('Bar (this Toast will not auto expire)', {

body: 'Bar (this Toast will not auto expire)',

As you may have noticed, `BToast` counts down similar to `BAlert`, in fact, it actually uses the same underlying engine that powers the countdown timer of `BAlert`, albeit with some minor adjustments. So, many of the same props are shared, including the `interval` props and others. So, similar quirks apply

As you may have noticed in that example, there was a built-in progress bar. This is triggered when using a value that is a `number` and when `progressProps` is not `undefined`. This was implemented because it can be difficult do modify the behavior of `BToast` when using a pure method, and the appearance of a ticking down progress bar is a "nice to have". Although, it is not out of the box behavior by Bootstrap, so its behavior is opt-in. This functions similarly to examples in `BAlert`
