0.20.0

Release notes for cobrapy 0.20.0

New features

• There is a new function inspired by
  cameo that can load models directly
  from BiGG or
  BioModels and by default will cache them
  locally (#995), for example,

  from cobra.io import load_model
  
  ecoli = load_model("iML1515")
  ylipo = load_model("MODEL1604280017")

Fixes

• Over a series of pull requests, @synchon has been modernizing parts of the
  codebase for Python 3.6+ (#993, #999, #1000, #1003)
• Upgrade the dependency python-libsbml-experimental to 5.18.3
