# Advanced layers: Containing multiple Layers in a LayerSet object
#==============================================================================
# What you can also do is make a LayerSet, which lets you
# conveniently call each Layer object just by its name. You can also specify
# the layer color using an RGB triplet e.g (0.1, 0.4, 0.2), an HTML hex color
# (e.g. #a31df4), or a CSS3 color name (e.g. 'gold' or 'lightblue'
# see http://www.w3schools.com/colors/colors_names.asp )
# The 'alpha' argument also lets you specify how transparent that layer should
# look when using quickplot (has no effect on the written GDS file)
