Cannot run the Layout-Aware example

[vmetodiev]

On the latest master branch commit, even if gdsfactory is installed, upon trying to run the "Layout-Aware Monte Carlo Simulations for Yield Estimation" example from the official documentation page, I get:

gdsfactory's API changes frequently, so it's possible that the latest versions of gdsfactory don't work with this example anymore. @SkandanC, any ideas on how far back of a reversion might be required?

I'll also mention that simphony is presently undergoing a pretty major refactoring to be released as v0.7.0 (and it will be incompatible with previous versions). The new API will be much prettier, in my opinion as the developer, so we probably won't be trying very hard to get the old versions of simphony to work with gdsfactory again but focus our efforts on the new one.
