"""Class for managing an IPython kernel inside of QGIS.
IPython normally runs kernels in seperate processes, but this setup is
limiting in the case of QGIS because external kernels cannot access the
data and variables that QGIS is working with. This class manages an
in-process kernel and is capable of launching external consoles that can
attach to the kernel.
IPython Consoles are run as external processes because they rely on
Version 2 of the PyQt api and QGIS is using Version 1 which is
incompatible.
