[wp-docs] Singleton Glossary Term

[Jacob Santos]

No. Singleton is not an object, it is a class pattern.

"Singletons are objects that exist globally and are the only one of 
their class." - Is correct

The rest is not. The Singleton class pattern puts constraints on exactly 
how many instances can be created, not the total number that are 
created, if that was the case then the majority of objects in WordPress 
would be Singletons because they are only created once. There are no 
Singletons in the WordPress library, actual all of the WordPress class 
library follows the normal object practices.

Searching Google for "Singleton object" only comes up with the Pattern. 
The Singleton is a pattern not an object, if anything it is a class 
methodology.
