derived from Molex KK 100 break-away header:
http://www.molex.com/pdm_docs/sd/022032041_sd.pdf

Usage (default values shown):

  use </path/to/libraries/header_pins.scad>  //full  headerPins(columns = 3, rows = 2, centerV = false, center = true, pitch = 2.52);  //simple  headerPins(3, 2);

columns = integer number of columns (X axis)
rows = integer number of rows (Y axis)
centerV = vertically center around base - fale places bottom at origin
center = center the array at the origin
pitch = distance between center of each pin

Note:

• the breakaway connector is a bit of a fudge and does not appear at the same
  Z height for centered/versus non centered; this should be largely irrelevant
