Ten tusscher et al 2004 and 2006 models

[MichaelClerx]

We fixed various unit errors in the Ten Tusscher et al. models, and created new exposures.
These currently show up in search, but so do the old uncorrected ones:

For some reason, the new exposures don't show up in the Electrophysiology list.

Requested action: Make the new exposures appear in "Electrophysiology". Get rid of the old exposures.
