Problem with sww2timeseries output file location is not consistent

[nick]

Matt Pittard installed anuga on C drive on a windows xp PC. He noticed that when running the gettimeseries.py in the cairns scenario in the anuga_demo. The graphs were outputted to the right directory but the csv files were outputed to the root directory.

Both the csv files and the graphs are produced in "generate_figures" in util.py. The file id "file_out" used for the csv file is never closed... maybe this is a problem... Look at line 1058

thisfile = file_loc[j]+sep+'gauges_time_series'+'_'+gaugeloc+'.csv'
fid_out = open(thisfile, 'w')

and around line 1087

s = '%.2f, %.2f, %.2f, %.2f, %.2f, %.2f, %.2f\n' %(t, w, m, vel, z, uh, vh)
fid_out.write(s)

Also to note is that this function is over lapped with the "make_plots_from_csv_file" function in util.py. It could be useful to use parts of generate_figures to make a function say "sww_gauges2csv" or edit sww2timeseries to output the timeseries data into files...
