Add SEIR network model using epiworldR

[gvegayon]

Example Description

Brief description of the model:
Using the R package epiworldR, we need to add an example of an SEIR network model. In the package (which has documentation here), the model is named ModelSEIR. It should feature a small-world network of size 10,000 with an average degree of 20 connections, aiming at an R0 of about 2 for 100 days. The simulation should start with a single infected case.

Programming language and package/framework:
Use epiworldR package in R.

Model characteristics:

• Perfect mixing model
• Network-based model
• Spatial model
• Continuous time
• Discrete time

Implementation Details

Use one of the examples included in the package as a referecen (it could be in the vignettes).

Dependencies

epiworldR installed as an R package

Proposed folder name:

01-epiworldr_seir_network
