class_docstr: Configure the quantization behavior by setting config variables.
  
  Note
  ----
  This object is backed by node system in C++, with arguments that can be
  exchanged between python and C++.
  
  Do not construct directly, use qconfig instead.
  
  The fields that are backed by the C++ node are immutable once an instance
  is constructed. See _node_defaults for the fields.
