install atomspace examples

[plankatron]

can octool do a git clone of the repos instead of downloading a tar.gz of master ? this way you could then have octool update with git pull in each repo.

-w option should be more explicit , in that it says it will download data sets for use with opencog not the opencog data set , you can get confused into thinking this would download the opencog repo?

The meta-issue is that, after discussing with @plankatron that there was no obvious way to run the examples in the examples/atomspace directory -- that entire directory is lost/hidden somewhere ... and those examples are currently the #1 best examples/tutorials that we have.
