master
Slightly simplified the calculation of alignment pattern spacing in a non-obvious way, adapted from David Evans's "Lean QR" project.
Moved QrCodeGeneratorDemo.java out of the package because it's an informal demo and not a core library feature; this also simplifies the Maven build process.
- In the project (top-level) readme file, kept one language's code example and moved all others out to language-specific readme files. - Added a readme file for each programming language implementation (port) if it didn't already have one, mostly by copying the project readme text, and then added/edited a couple of feature points.
Updated package version numbers.
