Re: Dynamically expanding target layer

["Randall C. O'Reilly" <oreilly@grey.colorado.edu>]

All of the data structures in pdp++ are dynamic, so it should not be
difficult.  For example, to create new units in a layer, in css script
code:

.layers.Target.units.New(1);  // create 1 new unit in "Target" layer

Connecting them is also not difficult (connecting 1st unit in each
layer):

.layers.Target.units[0].ConnectFrom(.layers.Hidden.units[0],
.layers.projections.Fm_Hidden);

you just need to create the projection in advance.  use a
"CustomPrjnSpec" as the projection spec.

note that you can only refer to layers, etc by name in css -- if you
want to do this in hard code, you'll need to either Find things by
name or know the appropriate indexes.
