added template, typo in readme

added NGCGUItemplate.ngc file to simplify new subs.  first 10 vars are
defined to keep some consitency from sub to sub.  machine vars first,
however they will be mostly un-implemented as my machine lacks such
controll so Ican't test fully/don't have the time energy for em.
created circle mill from annulus mill
added comment to get layer control folding properly
updated template for ngcgui
changed machine setting and spindle direction setting

using 3 and 4 for spindle rotation values simplifies life, also still
tweaking the "default" settings lists,but now wasting 1-15 on all
seems likea poor setup.
tweaking circle mill, plunge needs to be implemented

very tempting to just toss exisiting cycle and start from scratch
pulled circle pocket mill from net replaced numbered vars and preamble
added template and formatted numbers, opens but untested
fixed some variables that got renamed badly
restructureing template, adding default vars
fixed comments, added plunge initilizing

still in super beta
corrected typos, removed vestigal annulus moves and doubled plunge
fiddling with leadin, may not be real issue however
