default operation now works

made a bunch of changes to the format of the parser options in the code
for ease of reading.
output formats fixed

returned —out,—table to previous functionality
--measure now works

it seems that previous versions of aegean were not actually using the
input rms file. This has also been fixed.
reformat of test module

same tests but now using the new command line format
no test is done for hdu!=0 as I can’t find the file
