Base class for verification methods.
Once a verifier object is created, the verification can be started by calling the verify() method, which will return a promise that will resolve when the verification is completed, or reject if it could not complete.
Subclasses must have a NAME class property.

Cancel a verification.
We will send an m.key.verification.cancel if the verification is still in flight. The verification promise
will reject, and a VerifierEvent.Cancel will be emitted.

Synchronously calls each of the listeners registered for the event named
event, in the order they were registered, passing the supplied arguments
to each.

Get the details for reciprocating QR code verification, if one is in progress
Returns null, unless this verifier is for reciprocating a QR-code-based verification (ie, the other user has
already scanned our QR code), and we are waiting for the user to confirm.
Get the details for an SAS verification, if one is in progress
Returns null, unless this verifier is for a SAS-based verification and we are waiting for the user to confirm
the SAS matches.
Returns the number of listeners listening to the event named event.
The name of the event being listened for
Returns a copy of the array of listeners for the event named event.
Alias for removeListener
Adds the listener function to the end of the listeners array for the
event named event.
No checks are made to see if the listener has already been added. Multiple calls
passing the same combination of event and listener will result in the listener
being added, and called, multiple times.
By default, event listeners are invoked in the order they are added. The prependListener method can be used as an alternative to add the event listener to the beginning of the listeners array.
The name of the event.
The callback function
a reference to the EventEmitter, so that calls can be chained.
Adds a one-time listener function for the event named event. The
next time event is triggered, this listener is removed and then invoked.
Returns a reference to the EventEmitter, so that calls can be chained.
By default, event listeners are invoked in the order they are added. The prependOnceListener method can be used as an alternative to add the event listener to the beginning of the listeners array.

Returns a copy of the array of listeners for the event named eventName,
including any wrappers (such as those created by .once()).
Removes all listeners, or those of the specified event.
It is bad practice to remove listeners added elsewhere in the code,
particularly when the EventEmitter instance was created by some other
component or module (e.g. sockets or file streams).
