SUMEAN - get the mean values of data traces

sumean < stdin > stdout [optional parameters]

Required parameters:
power = 2.0 mean to the power
(e.g. = 1.0 mean amplitude, = 2.0 mean energy)

Optional parameters:
verbose = 0 writes mean value of section to outpar
= 1 writes mean value of each trace / section to
outpar
outpar=/dev/tty output parameter file

Notes:
Each sample is raised to the requested power, and the sum of all those
values is averaged for each trace (verbose=1) and the section.
The values power=1.0 and power=2.0 are physical, however other powers
represent other mathematical L-p norms and may be of use, as well.
