Detailed Description

Sudoku related structures.

  The L_Sudoku holds all the information of the current state.

  The input to sudokuCreate() is a file with any number of lines
  starting with '#', followed by 9 lines consisting of 9 numbers
  in each line.  These have the known values and use 0 for the unknowns.
  Blank lines are ignored.

  The @locs array holds the indices of the unknowns, numbered
  left-to-right and top-to-bottom from 0 to 80.  The array size
  is initialized to @num.  @current is the index into the @locs
  array of the current guess: locs[current].

  The @state array is used to determine the validity of each guess.
  It is of size 81, and is initialized by setting the unknowns to 0
  and the knowns to their input values.
