-//download.js v4.2, by dandavis; 2008-2016. [CCBY2] see http://danml.com/download.html for tests/usage
-// v1 landed a FF+Chrome compat way of downloading strings to local un-named files, upgraded to use a hidden frame and optional mime
-// v2 added named files via a[download], msSaveBlob, IE (10+) support, and window.URL support for larger+faster saves than dataURLs
-// v3 added dataURL and Blob Input, bind-toggle arity, and legacy dataURL fallback was improved with force-download mime and base64 support. 3.1 improved safari handling.
-// v4 adds AMD/UMD, commonJS, and plain browser support
-// v4.1 adds url download capability via solo URL argument (same domain/CORS only)
-// v4.2 adds semantic variable names, long (over 2MB) dataURL support, and hidden by default temp anchors
-// https://github.com/rndme/download
