Documentation/UserGuide/Data Output with cylindrical

Most output formats work seamlessly with cylindrical coordinates. Visualization packages such as VisIt can read Athena .vtk files and plot them in cylindrical coordinates automatically.

We have found it useful to use certain data post-processing functions with binary dumps. Thus we have added a coordinate system flag to the dump_binary.c function. Currently, this flag is either -1 for Cartesian coordinates or -2 for cylindrical (we made these negative to avoid confusion with the various Boolean flags). As usual, the default output formats are enrolled in the input files. This allows packages such as IDL to recognize which coordinate system is being used.

A large number of Matlab scripts for data analysis are now included in the /vis/matlab directory, some of which are useful in cylindrical coordinates.
