Documentation on types of Connections in ModelingToolkit.jl

Thank you for making ModelingToolkit.

My question concerns with the documentation of building the Component Library for Acasual modeling. In the example given in the documentation (RC - Circuit) [connect = Flow] is used to ensure the sum of currents is zero.

I want to know what other options of connections are available. As far as I know the other one is Stream but I am not sure of its exact implementation and purpose as I was not able to find adequate documentation.

Do let me know if I am missing some particular links/documentation.

Right now it’s missing and we need to write more docs around it.
