quantalEfficiencies = PhotopigmentQuantalEfficiency.(receptorTypes,[species],[source])

Return estimate of the fraction of absorbed quanta that lead to an isomerization.

Supported types:
Any

Supported species:
Any.

Supported sources:
Generic (Default).
None (returns 1 for all photoreceptor types)

The generic source returns the value 0.667 for any species or type. This
is currently the only interesting source implemented. The value comes from
Rodieck RW, The First Steps in Seeing, page 472.
