Add a repeat node type

It is similar to the map node but does the steps in a sequential way.

The input parameter should be a limit: int

This will require just like map_variable, there should be counter_variable which keeps track of the iteration.

Even conditional step could be something interesting. Local and local-containers should do this natively while depending on the transpilation for the other platforms.
