How can I create custom components?

Problem description: 

I don't see the exact component I'm looking for in the PLECS library. I'd like to be able to create it myself and add it to the library.


New components can be easily created in PLECS and added to customized user libraries. You can use existing PLECS components and modify them, or build a more complex component using multiple discrete PLECS components. Subsystems can also be made with multiple configurations for easy development and troubleshooting.
