PrintABlok openScad Blok Builder

**** UPDATED 03/07/2020 ****
Changed the Y and N (Yes and No) constants to +999 and -999 to avoid problems with connector socket angles of +1 or -1.
**** UPDATED 03/05/2020 ****
* Fixed bug that prevented cutting the down (bottom) face socket.
* Added fudge to socket angle to get around a SCAD cgal error when the angle was exactly 0 or 90 degrees.

I am a backer of Joe Larson's PrintABlok Kickstarter. He is developing a large set of models that can be used to create awesome mechs.

I have developed "baseBloks.scad" with a "baseBloks" main module that allows the creation of many types of standard and custom bloks. This module allows you to:

* Create a blok with any width, depth or height. By default the module creates the Joe Larson 16mm cube base blok.

* Specify for each of the four vertical faces if the edges of the face should be chamfered or plain. By default all edges are chamfered like Joe Larson's base blok.

* Specify for each of the six faces
