Morphelectrotonic transforms for branched cells. The passive properties are contained in a CellProps object pset.
Three possible transforms are provided based on a point of interest selected from the structure (see the BranchedCell interface): centripetal voltage attenuation (V-attn-cp) centrifugal voltage attenuation (V-attn-cf) and propagation delay (**unimplemented**), all for sinusoidal inputs of frequency omega.
In the first case, the value of a site is the log of the ratio of the amplitude of a voltage applied at the site to the amplitude recorded at the point of interest. The second case corresponds to a signal applied at the point of interest. The value is again the log of the applied to recorded amplitude ratio.
There are two possible display styles: scaled or colored. In the first segment orientations are preserved but lengths are scaled so the path length to a particular point is the value described above. Colored displays keep the physical shape and size of the cell, but color code segments according to the mapping defined in the ColorTable coltab.
