Inspired by: @NitsanBlau

What is the feature being requested?

GDS/Oasis are convenient ways to pass the data between researchers and to store for future use. It will be helpful to be able to import back what has been exported.

What are use cases for this feature?

Any number of co-programming set-ups.

QComponent from GDS import

Import GDS shapes
try to convert to shapely intelligently
add properties, assign layers, pos/neg etc.
add default options for position, rotation, scaling for the whole thing

The above is from #23 , so will close 23.
