version 1.01 include:
* Added parameters for 5167 Avery (tm) stock. Also added many new
Avery (tm) parameters.

string anywhere they want. Particular use is for numbering the pages.

* Added y_gap to Avery(tm) labels
* Updated calibration plot in BasicData to arbitrary paper size
* Added all of the component and label definition stuff.
