* preview code I dropped on jackie today. only supports document collections.
* saving work in progress
* update arangoexport to fully use ManagedDirectory object (arangoimport still needs work).
* migrate remainder of import to using ManagedDirectory objects
* correct spelling within activateEncryption(): encription to encryption
* forgot to fix up graphExport for managed directory. luckily unittest noticed.
* add test read of gzip json file
* add readGzip to our fs object
* add TRI_SlurpGzipFile function
* add code to bridge javascript fs.readGzip to TRI_SlurpGzipFile
* correct the return type used by JS_ReadGzip
* add gzip test for jsonl type export
* add remain gzip versions of existing export tests
* add import tests of gzip files
* activate encryption in enterprise to enable fs.readDecrypt()
* bug fix: allow encryption to enable in empty directory if EncryptionFeature active.
* add JS_ReadDecrypt to enterprise build. Current used for unit tests.
* enterprise build needs EncryptionFeature added to build to support TRI_SlurpDecryptFile()
* add TRI_SlurpDecryptFile() to aid in unit test of encrypted stuff
* missing newline at end of file.
* add fs.readDecrypt when available
* add test of encrypted json array export
* correct progress meter when gzip involved
* move from using ManagedDirectory::File to ManagedDirectory::readableFile calls
* create version of readableFile that uses file descriptor as param
- split utility functionality into its own file
- add module loader so we can have modules
- move all testsuites into own files
- remove complicated testcase joining / splitting methods
