Alpha release supporting major versions of macOS and Windows

The executables in this alpha release have been tested on macOS 10.12 (Sierra), 10.11 (El Capitan), 10.10 (Yosemite), and 10.9 (Mavericks); and on 32-bit and 64-bit versions of Windows 10, 8.1, 7, and Vista. Windows executables are now fully statically linked.

Alpha release with optimized executables statically linked to stdc++ library

The executables in this alpha release are smaller than in previous releases (3-6 MB rather than 10-64 MB), faster (graphs produced in 100 msec), and are statically linked to the stdc++ library. On macOS a single executable nominally targets macOS versions 10.6-10.12, unlike the previous alpha releases which ran only on macOS 10.12.

Alpha release of YW 1.0 with builtin Graphviz library

This is the first release of YW that can produce SVG images of workflow graphs using a statically linked, minimal Graphviz library. A separate Graphviz installation is no longer required on the user's computer. However, YW can still output DOT format for use with a full-featured Graphviz installation, e.g. if other graphics formats are needed.
