Invalid import clause in ThirdSpecies

[henrikt-ma]

The import clause in ModelicaByExample.Components.LotkaVolterra.Examples.ThirdSpecies is invalid; quoting System Modeler:

Error: ModelicaByExample.Components.LotkaVolterra.Examples.ThirdSpecies [2:3-2:3] Invalid qualified import. ModelicaByExample.Components.LotkaVolterra.Components.RegionalPopulation.InitializationOptions.FixedPopulation is an enumeration element and ModelicaByExample.Components.LotkaVolterra.Components.RegionalPopulation.InitializationOptions is a type but a qualified import must reference a package or a package element.

A simple fix is to simply not do the import:

--- a/ModelicaByExample/Components/LotkaVolterra/Examples/ThirdSpecies.mo
+++ b/ModelicaByExample/Components/LotkaVolterra/Examples/ThirdSpecies.mo
@@ -1,8 +1,7 @@
