/*
  Macros for declaring public API
  ===============================

  API function declarations should be decorated with PUBLIC_API prefix. API
  classes should have PUBLIC_API marker between the "class" keyword and
  the class name.

  See: https://gcc.gnu.org/wiki/Visibility

  TODO: Use better name than PUBLIC_API - not all public API classes should
  be decorated with these declarations but only these whose implementation
  is inside the library (so, not the ones which are implemented in headers).
