BioNetGen-2.8.1

New Features

• New action writeCPPfile writes a C++ header file that requires CVODE and encodes the model ODEs.
  This allows for ODE simulations of the model directly from other C++ software
• New action writeCPYfile writes a C file that requires CVODE and encodes the model ODEs.
  This allows for ODE simulations of the model directly from other C software. Additionally, this
  file is written with the Python ctypes module in mind, making it easier to make direct calls to
  a shared C library from Python.

Minor changes

• Updated underlying NFsim version to 1.2.2
• Minor bugfix where the reported unique species didn't account for certain species resulting in an incorrect count.
