MatchVector, AnnotationMatch, TokenMatch are now MatchData
MatchData is value_type of Match which now has get_value/set_value
Match has also copy construction working properly now
Default value for Match holds MatchVector so adding $m:_M var in grammar works as intended.

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

MatchResult - change constructor so when you provide Match it defaults to matched = true.
TokenCondition - be a bit defensive about possibility of inner predicates changing $_

It's a tuple boolean/Match Value - "is it matched?"/"actual match"

Previously effectively agreement was checked on all categories,
even if a lexeme's tag didn't have some of the selected categories.
That led to treating such lexeme as not agreeing with one that had
more matching categories, even if it was agreeing on all categories
that were present.

Underlying issue was temporary table of remaining lexemes for a token not being
updated (emptied) if only underspecified lexemes of the token met an agreement.
Effectively the token was left in its original state i.e. with all
original lexemes present, both those that were underspecified and the remaining
ones that did not met a weak agreement that was otherwise met via the
underspecified lexemes.
