Log:
Extended tracing to write extended fileformat, i.e. children of Hidden nodes.
Nicely only a tiny change is needed in Hat.hs, calling the new recordChild function in fun_i combinators when the parent is hidden. So the additional child information only costs time when there are such children.
Most changes in hat-c.c. New buffer for every Hidden node that has children (but not those that do not). This buffer enables simple reading and updating of the child pointer of a Hidden. The buffer is only written at termination time, so unfortunately the space requirements of a traced program are no longer proportional to that of an untraced one. However, I believe that in practise the buffer will never be large.
The buffer is currently a linked list of arrays. A tree structure would allow faster lookup, but the existing FiniteMap is unsuitable (only for pointers).
hat-check has been modified to make appropriate checks.
