Supports *hot reloading* of Angel3 servers on file changes. This is faster and more reliable than merely reactively restarting a `Process`. This package only works with the [Angel3 framework](https://pub.dev/packages/angel3_framework).

## Usage
This package is dependent on the Dart VM service, so you *must* run Dart with the `--observe` (or `--enable-vm-service`) argument!!!
Usage is fairly simple. Pass a function that creates an `Angel` server, along with a collection of paths to watch, to the `HotReloader` constructor. The rest is history!!!
The recommended pattern is to only use hot-reloading in your application entry point. Create your `Angel` instance within a separate function, conventionally named `createServer`.

## Customising Response Header
Additional parameters can be passed to the `Runner` class to:
1. Remove headers from HTTP response.
2. Add headers to HTTP response.
For example, the following code snippet removes `X-FRAME-OPTIONS` and adds `X-XSRF_TOKEN` to the response header.
```dart
void main(List<String> args) {
// Remove 'X-FRAME-OPTIONS'
var removeHeader = {'X-FRAME-OPTIONS': 'SAMEORIGIN'};
// Add 'X-XSRF_TOKEN'
var customHeader = {

};
Runner('example', configureServer,
removeResponseHeaders: removeHeader, responseHeaders: customHeader)
.run(args);
}
```
## Run-time Metadata
At run-time, you may want to know information about the currently-running instance, for example, which number instance. For this, the `InstanceInfo` class is injected into each instance:
