Small, fast, simple and streaming project scaffolder for myself, but not only. Supports hundreds of template engines through the @JSTransformers API or if you want custom `render` function passed through options

var cof = require('./_cof');

  if(typeof it != 'number' && cof(it) != 'Number')throw TypeError(msg);
  return +it;
};
