**PROGRAM BROKEN

MAJOR UPDATE --- broken release

fixed start and end positions of all characters

adjusted some margins. margins still need adjustment,
characters do not line up when overlayed. check number 2
start point.

series algorithm needs to be re-written to be compatible
with incremental positions
second release version
---

fixed small formatting issues with the text
