Allows the following:

>>> import kfactory as kf
>>> b = kf.kdb.DBox(100.0005, 100.0005)
>>> print(b)
(-50.00025,-50.00025;50.00025,50.00025)
>>> print(kf.kcl.to_dbu(b))
(-50000,-50000;50000,50000)
>>> print(kf.kcl.to_um(kf.kcl.to_dbu(b)))
(-50,-50;50,50)
>>> print(kf.kcl.to_um(kf.kcl.to_dbu(5.00005)))
5.0

This works for the following types:

int
| kdb.Point
| kdb.Vector
| kdb.Box
| kdb.Polygon
| kdb.Path
| kdb.Text

<->

float
| kdb.DPoint
| kdb.DVector
| kdb.DBox
| kdb.DPolygon
| kdb.DPath
| kdb.DText
