VLog version 1.1.1

Bugfix release.

VLog version 1.1.0

This is mostly a bug fix release, but it also alleviates a limit in the tuple size, by getting rid of the SIZETUPLE constant.

VLog version 1.0.1.

Modified compilation, to have lz4 statically linked, so that it gets included in the binaries, so that the binaries don't depend on the existence of an lz4 library.

Release 1.0.0

This is the first "official" release of VLog, a Datalog engine combining a column-based memory layout with novel optimization methods that avoid redundant inferences at runtime, resulting in high efficiency in terms of memory usage and speed.
