//
// File defining fields in the Yap_heap_codes global structure
//
// these fields used to spread all over the place, because they must be used in 4 ways:
//  - they must be defined somewhere
//  - they have an #ifdef to get a shorter name
//  - they must be initialised somewhere
//  - they must be restorable and collectable (from the atom gc).
//
//
// The defs include 4+ components:
//   Type
//   name in structured
//   global name
//   init code and restore code (optional)
//
//
//
// MkAT (MkAtomTerm) cvts from a predefined atom to a term
// MkPred constructs a pred_entry
// MkOp gets an opcode
// void does nothing
// =VALUE inits as VALUE
// Init... sets up call to InitFunc
// Restore... sets up call to RestoreFunc
//
