## Features ### Open * Now returns the activeDocument after opening the file. ### JSLayer() * Removed semicolon from output. ### Document * Added FullName() which returns path to the .psd file. * Changed Filename() to DumpFile(), as Filename was misleading. * Dump function now saves the file as well, to help reduce the frequency of de-syncs. * Dump function now saves json files alongside the .psds instead of in a separate data folder- encountered issues when using the package as a module in go 1.11beta2. * Added Save() ## Testing * Added TestDocument_Save * Added TestDocument_Dump ## Misc. * Renamed pkgpath to pkgPath, to better fit go's standards. ## Fixes * DoAction now runs correctly.
