Presenting BoldChatViewController from Storyboard

If the view settings contains the following styles, the view controller can be presented without an embedding navigation controller:

formSubmitStyle = BoldChatViewSettingsFormSubmitStyleLastCell
endChatStyle = BoldChatViewSettingsEndChatStyleOnChatView

Steps to add without navigation controller

Add a view controller to the storyboard.
Set the custom class of the view controller to BoldChatViewController.
Add a segue from the presenter view controller to the BoldChatViewController

Add the following lines to the view controller code, that handles the segue:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([segue.identifier isEqualToString:@"<name of the segue displaying the navigation controller>"]) {
        BCAccount *account= [BCAccount accountWithAccessKey:@"<access key from web setup>"];
        BoldChatAccountSettings *accountSettings = [[BoldChatAccountSettings alloc] init];
        accountSettings.account = account;
        accountSettings.visitorId = <customer id to track the user>;
        
        BoldChatViewSettings *viewSettings = [[BoldChatViewSettings alloc] init];
        viewSettings.formSubmitStyle = BoldChatViewSettingsFormSubmitStyleLastCell;
		viewSettings.endChatStyle = BoldChatViewSettingsEndChatStyleOnChatView;
        
        BoldChatViewController *bvc = (BoldChatViewController *)segue.destinationViewController;
        [bvc configureWithAccountSettings:accountSettings viewSettings:viewSettings language:nil];
    }
}

Start the chat
```
[bvc start];
```

Steps to add with navigation controller

Add a navigation controller to the storyboard
Add a view controller to the storyboard
Set the custom class of the view controller to BoldChatViewController
Add a "root view" relationship segue from the navigation controller to the BoldChatViewController
Add a segue from the presenter view controller to the navigation controller

Add the following lines to the view controller code, that handles the segue:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([segue.identifier isEqualToString:@"<name of the segue displaying the navigation controller>"]) {
        BCAccount *account= [BCAccount accountWithAccessKey:@"<access key from web setup>"];
        BoldChatAccountSettings *accountSettings = [[BoldChatAccountSettings alloc] init];
        accountSettings.account = account;
        accountSettings.visitorId = <customer id to track the user>;
        
        BoldChatViewSettings *viewSettings = [[BoldChatViewSettings alloc] init];
        UINavigationController *navc = (UINavigationController *)segue.destinationViewController;
        BoldChatViewController *bvc = [navc viewControllers][0];
        [bvc configureWithAccountSettings:accountSettings viewSettings:viewSettings language:nil];
    }
}

Start the chat
```
[bvc start];
```
