PerformanceEntry class
The object encapsulates a single performance metric that is part
of the performance timeline. A performance entry can be directly
created by making a performance mark or measure (for example
by calling the mark() method) at an explicit point in an
application. Performance entries are also created in indirect
ways such as loading a resource (such as an image).
instances will always be one of the following subtypes:
