This commit creates a LEF abstract view of the top level, which 

establishes all the pin names, positions, classes, and uses.  Adds
a script which uses the LEF abstract view to annotate the top level
layouts for caravel and caravan with the chip pins (not yet run---
waiting for a valid top level layout after top-level routing).
Also:  Updated the copyright block to increase the chip version
number and update the date.

#
# Generate the top level pins for caravel and caravan.
# Most of the work is done by importing the LEF file for caravel (which has the
# same content as caravan), then formatting the labels.
#
# Run this script from the mag/ directory
#
# This script may be run on a layout that already has pins without affecting the
# layout.
