[Users] dependencies & CST warnings

[Erik Schnetter]

Bernard

The test suite in LSUThorns/Vectors is self-contained, and you need only this thorn to run it. This will indicate (on stdout) whether there was an error or not.

However, to fit into the Cactus test suite mechanism, the test suite needs to output a file. This requires a few other thorns, including PUGH and IOASCII. The warnings that are reported are harmless, since the content of the file does not matter -- what only matters is that there is at least one file generated when the self-test succeeds.

In general, scheduling a routine into a non-existing schedule bin means that this routine is not executed. In many cases, this is just the right thing to do. In other cases, this is e.g. due to an error in schedule.ccl, which is why we moved from "silently not scheduling" to reporting warnings about these. In this case, the warnings are harmless and no need to worry, since the thorns Boundary and SymBase are not actually required by CartGrid3D. One wishes there was a way to indicate this in the schedule.ccl so that these warnings could be omitted.
