Type commandCopyAndLoadDemo('xxx') to copy all files from auto/07p/demos/xxx to the
current user directory. Here 'xxx' denotes a demo name; e.g.,
'abc'. Note that the 'dm' command also copies a Makefile to the
current user directory. To avoid the overwriting of existing
files, always run demos in a clean work directory. NOTE: This
command automatically performs the commandRunnerLoadName command
as well.
