Removed references to 'ASC_BIG_BUGMAIL' and 'ASC_MILD_BUGMAIL'

21 Centralized redirection of standard streams to file.
22
23 Many ASCEND routines print messages. In a testing context, it
24 is usually preferable to have output redirected to a file. This
25 module provides a centralized location for this code (which may
26 end up somewhat platform-dependent).
