Another PiGRRL"0.2" was designed based on Pocket PiGRRL(and PiGRRL2 also).
Requirements are almost the same as PiGRRL.
The cost should be reduced by adoption of Raspberry Pi Zero and 2.2"LCD.
On the other hand, the complicatedness of soldering and assembling will
wipe out the advantage of the cost.

"pizero_225.123dx" has been fixed.
-Unnecessary hidden sketches have been deleted.
-The following problem was pointed out.
When "show sketch" is done, a lot of unnecessary sketches appear, and the operation of 123D becomes dull.
That problem will disappear.
