local copies of zip "data tables" corrupt
morpho - general
The example is soong.37.2 on the dev metacat (search for soong). The data package contains zip files as "data tables". The zip files are intact in the cache folder (can be expanded). After syncing remote->local, the zip files in the data folder are corrupt (contents can be listed but not expanded).
This seems to cascade into exporting when local data are present as well. With no local data, exporting seems to work fine.
In DataPackage.download method, there were local codes to handle download data. They used Reader and Writer method :(. I used serializeData method, which were fully tested, to replace the local code. After do that, it works for Jim, oliver and me.
The bug was fixed by above solution.
