Continuous HPI data

Dear MNE python,

I have been working on a project which uses the HPI coils to track lip
movement, and I was hoping to be able to use MNE to be able to tell me the
coordinates of the moving HPI coils continuously. I know this is used in
the cHPI program through the info[dig] ? possibly, but I was hoping for
some insight into this problem and see what type of code I need to obtain
those continuous HPI coil coordinates.

Thank you so much,

Aditya Singh

There is a private (experimental/unsupported!) function
mne.chpi._fit_device_hpi_positions in the `master` version (will be in
0.15) that you could use for this purpose, courtesy of Luke Bloy
<https://github.com/mne-tools/mne-python/pull/4069>. Because it is private,
keep in mind that it could go away or change without notice. However, if
you do use it, please open issues on GitHub for any issues you find, as it
will help us vet the cHPI localization code.
