// The map file is kept as a doubly-linked list of sections, each of which has
// a doubly-linked list of lines in that section. A header is used to point to
// the first section, and also contains a pointer to any lines that appear
// before the first section (usually only comment lines) - it also keeps the
// current line and section pointer.
//
// All the linked lists have a dummy header and tail, with the tail pointing
// back on itself (this simplifies the logic for list manipulation)...

// The dummy head/tail nodes make it easy to keep track of the start and
// end of the list (we never have to worry about updating the head and tail
// pointers in the owning data structures, since they never change). It does,
// however, make for some obtuse cases in the add/delete node code.
