A condition that repeateadly matches an array of conditions returning resulting vector of vectors.

First draft of Match value type with some tests. MatchVector does not yet properly implement first/last token, hence a test fails, and AnnotationMatch is pretty much a stub.

That forced antlr to run every time. The workaround is to remove the output directory
so files are generated from clean slate, thus have proper time stamps.

The agreement stuff isn't implemented yet.

Add the tagset-symbol-getter operator (GetSymbols), bump required Corpus2 version to 1.0.2 since new features are needed.

RelativePosition operator, represented by "+" in WCCL (at least initially). Returns Nowhere for Nowhere, or a Position shifted by given offset to the position given (Begin and End are first translated into normal Positions).

Claryfing comment for linux antlr lib (it should only be included for final execs not for intermediate libs)
