Missing connection private member

[glennsarti]

The Example backend references the Connection parameter in Connect and Disconnect (e.g. https://github.com/poshbotio/PoshBot.Example.Backend/blob/master/PoshBot.Example.Backend/Classes/ExampleBackend.ps1#L15), however the Connection is never set during initialisation.

Perhaps a better example would be to create the relevant connection object as there is already a ExampleConnection class.

e.g.

    # Constructor
    ExampleBackend ([string]$Token) {
        # Implement any needed initialization steps

        # Example connection settings
        $conn = [ExampleConnection]::New()
        $this.Connection = $conn
    }
