Add example to avoid warning on R CMD check.
Change the package name to "vimcom.plus".
The package vimcom will no longer be accepted on CRAN if the calls to
Rf_addTaskCallback and Rf_removeTaskCallbackByName are in vimcom.c, but
these two functions are required to automatically update the Object
Browser. Solution: Create two packages: vimcom.plus and vimcom. The
vimcom.plus package includes Rf_addTaskCallback and
Rf_removeTaskCallbackByName calls and their stable versions will be
released at http://www.lepem.ufc.br/jaa/vimcom.plus.html while the
vimcom package will not have these calls and will be uploaded to CRAN.
Update.
