# Version History
#
# v0.1 - Script only generates a multi-sided mesh object,
# initial release for testing. 3/12/11
#
# v0.1.1 - Added 'C'-type beam, updated to work with
# api r35499. 3/13/11
#
# v0.1.2 - Totally changed the way beams are created, size
# is now calculated based off width, length, & height
# (x,y,z). Added ability to taper beams as well.
# Add 'L' - type beam
# Add 'T' - type beam
# Add 'I' - type beam
# Creates a rectangluar, or 'C', or 'L' or 'T' or 'I' - type beam.
