Basic text renderer implemented as an OpenSCAD module, allowing the generation of text from a string directly in OpenSCAD.

Currently uses a HD44780 LCD controller dot matrix font.

Two versions exist, TextGenerator.scad covers all OpenSCAD versions before 2015.03. Version 2015.03 deprecated the assign module, allowing for more convenient C like assignments. Therefore I've created a new version removing the deprecated module warning generated by this version.
