**resource.go/assets.go** * renamed `resources.go` to `assets.go` * added dark glyphs - located in assets.go -> assets/glyphs/dark/ * moved original glyphs - located in assets.go -> assets/glyph/light/ **glyphbanner.go** * added option to make glyphs vertical and/or dark **rpcg.go** * Added a random portal code generator this function takes no args and returns a string **README.md** * Fixed some typos (probably more to be fixed) * Added example of vertical portal banner * Added list of options for banner creation * Added example of ``nmslib.RndPortal()`` usage **go.mod** * updated go version to 1.16
