Clearing gdsLibrary is not simple anymore with new duplicate detection

[gyger]

In the past I used the trick to write the following code somewhere in my Jupyter Notebook to initialize a new GDS library.

gdspy.current_library = gdspy.GdsLibrary()
cell = circle_grating(width=10)
gdspy.write_gds('tmp_test.gds', unit=1.0e-6, precision=1.0e-9)

With the new duplication detection, a cell is not added anymore to the library if it was added before. Somehow Picwriter does not realize that the library has been reset.

The solution currently is to also reset the dictionaries in the toolkit

gdspy.current_library = gdspy.GdsLibrary()
tk.CURRENT_CELLS = {}
tk.CURRENT_CELL_NAMES = {}

One could e.g. provide a function in the toolkit tk.reset_database().

Thanks for the bugfix. I've added a reset_database function to the toolkit, as you suggested. If you think of a better way of resetting these attributes let me know. I've had the same problem as you and don't know what the most elegant fix is.
