Is your feature request related to a problem? Please describe.
It could be useful to have a Generic priority queue.

Describe the solution you'd like
To add a Generic Priority Queue, capable of handling primitive data types, as well as custom classes, to be used for specific problems or algorithms without complications.

Additional context
I can add this functionality myself, tested and ready to be used with the basic operations of a queue, and some useful methods.
