/**********************************************************************
                ecount()
***********************************************************************
"error counter"
This star compares two data streams for "equality".  (Since the input
streams are floating point, a guard band is used.) An output stream
is created, with 'zero' output for equality, and 'one' if there is a
difference.  (Note: the output stream is optional--if no star is
connected to the output, there is no output.)
Param. 1 selects an initial number of samples to be ignored for
the final error tally (used during training sequences); default zero.
Param 2 sets an index, after which a message is printed to stderr for
each error.  It defaults to "infinity", i.e. no error messages.
This star prints a final message to stderr giving the error rate
(errors/smpl), disregarding the initial ignored samples.
