On(event string, task interface{}) error
  - Add a Event. task must be function. Throws an error if the event is duplicated.
   
Fire(event string, params ...interface{}) ([]reflect.Value, error)
  - Fires the task specified with the event key. params are the parameter and
  [] is the returned values of task. Fire Triggers the event and wait for it to
  end until it goes to execute the following codes.
  
FireBackground(event string, params ...interface{}) (chan []reflect.Value, error)
  - Fires the task specified with the event key. Unlike Fire it runs the event in
  background in go routine. It triggers the event but does not wait for the event
  to end. It writes the returned values of the event in a channel and returns the
  channel of reflect.Values. You can get the returned values by reading the
  channel (IE. ret := <- returned channel).
  
  - As FireBackground does not wait for the event to end first, if your program 
  exits it will stop any running event that did not finishes. So make sure your
  background events exits before ending the program.   


Clear(event string) error
  - Delete a event from the event list. throws an error if event not found.
  
ClearEvents()
  - Deletes all event from the event list.
  
HasEvent(event string) bool
  - Checks if a event exists or not. Return true if the event list have a event with 
  that key.  false otherwise.
  
Events() []string
  - Returns all the events added.
  
EventCount() int
  - Returns count of the events. If none found return 0;
