Some examples use deprecated workspace functions.

The workspace functions (e.g. CVodeGetWorkSpace, CVodeGetLinWorkspace, CVDiagGetWorkspace) are deprecated, but they are still used in many examples, so building the examples generates compiler warnings such as

cvDirectDemo_ls.c: In function ‘PrintFinalStats’:
cvDirectDemo_ls.c:871:3: warning: ‘CVodeGetWorkSpace’ is deprecated: Work space functions will be removed in version 8.0.0 [-Wdeprecated-declarations]

I don't think the examples should continue to use deprecated functions--ideally they should demonstrate recommended usage patterns. It appears the functions are only used as part of a display of summary statistics, so removing the calls should be straightforward.

Thanks for reporting this. You are correct, these functions should no longer be used in the examples.
