Code generation engine for the NEURON modeling language

 The NMODL Framework is a code generation engine for the
 NEURON MODeling Language (NMODL).
 It is designed with modern compiler and code generation techniques to:
   * Provide modular tools for parsing, analysing and transforming NMODL
   * Provide easy to use, high level Python API
   * Generate optimised code for modern compute architectures
     including CPUs, GPUs
   * Flexibility to implement new simulator backends
   * Support the full NMODL specification
