updated narsc workbooks

Forked it.  PR in.  

We really need a convenience method that says - read the shapefile DB AND get the geometries for X or X:Y or whatever.  Having to do one, then the other seems archaic.

00 showing that `!` is used for shell commands - at end.

For 04_Spatial_Weights - Do we have a method to visualize the contiguity?  For example - someone might have no idea what Bishop contiguity is (as evidenced by our recent conference call where ideas of contiguity are divergent baed on domain).

Game of life is super cool!

We should chat re: markov methods and parallelization - I have kept off the reading list to limit the scope a bit (and because they are quite new to me), but I think that the Monte Carlo Markov Method simulation is a place where we can parallelize some low hanging (potentially) fruit.

In 99 are you assuming that connectivity will be bad?  I altered to actually run the command, but perhaps this is not what you intend?  Also just visualizing inline - showman() func. is small.

Diff via git is terrible as prompt numbers always differ...major changes in 00, 04, and 99.
