[Mne_analysis] reconstruct virtual MEG channels in source-space

hi Eric,

please have a look at:

https://martinos.org/mne/dev/auto_examples/inverse/plot_compute_mne_inverse_epochs_in_label.html
<https://martinos.org/mne/dev/auto_examples/inverse/plot_compute_mne_inverse_epochs_in_label.html#sphx-glr-auto-examples-inverse-plot-compute-mne-inverse-epochs-in-label-py>

using apply_inverse_epochs you can get time courses of a label / vertice in
the brain over epochs.
you can then pass this tfr_* functions.

this should hopefully help.

if you want look at power in source space you can also use DICS:
