Mulberry2020 - Two-layered, self-organizing multicellular structure where all cells are of the same genotype

This model generates a two-layered, multicellular structure from a simple cell-cell signaling model. The cell signaling model is described by a system of ordinary differential equations, and is coupled with a cellular potts model. The model is in the MorpheusML format (https://morpheus.gitlab.io). The model will initialize with a random configuration of cells (which are all of the same type) which will then self-organize to form a two-layered structure. This file was used to produce Figure 10 in Mulberry and Keshet, 2020.
