@implementation NumberInputController
 
/*
Implement one of the three ways to receive input from the client. 
Here are the three approaches:
                 
                 1.  Support keybinding.  
                        In this approach the system takes each keydown and trys to map the keydown to an action method that the input method has implemented.  If an action is found the system calls didCommandBySelector:client:.  If no action method is found inputText:client: is called.  An input method choosing this approach should implement
                        -(BOOL)inputText:(NSString*)string client:(id)sender;
                        -(BOOL)didCommandBySelector:(SEL)aSelector client:(id)sender;
                        
                2. Receive all key events without the keybinding, but do "unpack" the relevant text data.
                        Key events are broken down into the Unicodes, the key code that generated them, and modifier flags.  This data is then sent to the input method's inputText:key:modifiers:client: method.  For this approach implement:
                        -(BOOL)inputText:(NSString*)string key:(NSInteger)keyCode modifiers:(NSUInteger)flags client:(id)sender;
                        
                3. Receive events directly from the Text Services Manager as NSEvent objects.  For this approach implement:
                        -(BOOL)handleEvent:(NSEvent*)event client:(id)sender;

-(BOOL)inputText:(NSString*)string client:(id)sender
{
        //Return YES to indicate the the key input was received and dealt with.  Key processing will not continue in that case.  In
        //other words the system will not deliver a key down event to the application.
        //Returning NO means the original key down will be passed on to the client.
        NSLog(@"%@", string);
        return NO;
