 Creates an observer from a notification callback.
 
 #### Arguments
 1. `handler` *(Function)*: Function that handles a notification.
+2. `[thisArg]` *(`Any`)*: Object to use as `this` when executing `handler`.
 
 #### Returns
 *(Observer)*: The observer object that invokes the specified handler using a notification corresponding to each message it receives.

 Computes the average of an observable sequence of values that are in the sequence or obtained by invoking a transform function on each element of the input sequence if present.
 
 #### Arguments
 1. `[selector]` *(`Function`)*: A transform function to apply to each element.

 #### Returns
 *(`Observable`)*: An observable sequence containing a single element with the average of the sequence of values.
