Phidl

Bugfixes
- Under the hood

New features
- Added label_aliases=False default option to quickplot. Do quickplot(D, label_aliases = True) to draw text with aliases on it
- Added Device.extract(). See the tutorial for details
- Device.add_polygon() can now receive lists of polygons, and will return lists in kind

Changes
- pg.snspd() and pg.snspd_expanded() can now be defined using any 2 constrains of: xsize, ysize, or num_squares.
- Nomenclature change on pg.fill_rectangle(), from exclude_layers to avoid_layers
- Changed pg.ytron_round() variable names, fixed layer error on cross

Bugfixes
- Fixed SNSPD squares calculation and added num_squares constraints

New features
- Added ability to make "alias" for DeviceReference. See the tutorial
- Can now use Port.x and Port.y instead of calling Port.midpoint[0] and Port.midpoint[1]
- Added Device.size property. Returns the equivalent of [Device.xsize, Device.ysize]
- Added include_layers to pg.fill_rectangle, allowing you to override exclude_layers
- Added pg.circle(), pg.cross(), and pg.ellipse()

Changes
- None

Bugfixes
- Fixed route_manhattan, had issue with using Device.add() instead of Device.add_ref()
- Fixed pg.snspd layer = 0 by default
- Fixed Port.endpoints

Changes
- phidl.geometry.route() works still but is being deprecated, will now be in phid.routing.route_basic(). pg.route() will be deleted in the near future

New features
- Several new photonic geometries by Sonia Buckley
- Advanced Manhattan routing written by Jeff Chiles

Bugfixes
- Very likely we added more bugs than we fixed in this version!

Bugfixes
- Fixes to phidl.geometry.hecken_taper()

Changes
- pg.taper() now has a default argument of width2=None

New features
- Fill tool (phidl.geometry.fill_rectangle) now allows you to invert the fill
- New function pg.invert() which will perform a boolean inversion on elements

Bugfixes
- Problem with route() and inset() caused by implementation of Layer(). You can now pass route() and inset() a Layer and it will parse it correctly
