manually fixed 1D ASCII output files:

* added missing comment lines at the top # 1D ASCII output created by CarpetIOASCII # * fixed comment line # column format: it tl rl c ml ix iy iz time x y z data into # column format: 1:it 2:tl 3:rl 4:c 5:ml 6:ix 7:iy 8:iz 9:time 10:x 11:y 12:z 13:data removed unneeded copy of parfile git-svn-id: http://svn.cactuscode.org/arrangements/CactusNumerical/Dissipation/trunk@27 850bcc8b-0e4f-0410-8c26-8d28fbf1eda9
