Detailed Description

Performs breeding and migration in one, migration rates are backward rates.

Inherits parameters from LCE_Breed_base and LCE_Disperse_base. Population size is constant, There is no demographic stochasticity with this LCE. The number of colonizers of extinct patches can be set differently from the patch carrying capacities.
