Release notes for cobrapy 0.15.2

New features

• We introduce a new tolerance attribute both on the global Configuration object as well as Model. The default for this is 1E-07. Many functions that use a zero cut-off will now use the set model tolerance value by default. This value can still be set manually via function arguments but attempting to set a threshold that is lower than the model tolerance now raises an error.

Fixes

• Geometric FBA now has a processes argument with a default of 1 which can be used for parallel processing.
• Clean up the sampling code and make it respect global defaults.
• Many SBML improvements, please see #835 for details.
