Introduce TypeTermTable as an alternative to TermTable dedicated to
types. A "type term" declaration has a type builder: an expression
which creates the corresponding SNode.
To access term's features on can use FeatureReferenceExpression.
The new _ExpectType_ _RecoverType_ rule tables are automatically added
to the user's 'types' aspect and serve to extract types from types.
AssignType and RecoverType pseudo-constraints can be used to
extract/assign or just extract the type, correspondingly.
Instead of the hack that that uses session parameters to pass
parameters to expandMacro, use directly `withParams` method
on macro token. All parameters are mapped to corresponding fields.
Introduce CustomSessionParameter to access parameters in
TemplateApplicationSession.
Expand macro passes the rule's input to nested macro calls.
This adds the macro input as the dependency of the rule's input.
As a result, incremental processing starts working in some cases.
RulePlanHandler does not rely anymore on fixed total order of
input nodes in a given rule template. An update constitutes a list
of rules/reqs generated for a pair template+input node.
All hacks that use sets of rule IDs removed.
Also, support for "new" and "dropped" rules removed, incremental algorithm
no longer supported.
Refactor supervisor/feedback consumer to support feedback basis.
Track (in)validated rules tags in RulePlanHandler.
Both (in)- and validated rules cause associated feedback to be cleared.
Disable passing SessionToken in WatchingIncremental strategy;
this forces the correct journal recording but turns off incrementality.
Optionally produce partial program in incremental mode.
A partial program includes all "static" rules plus the "required closure"
of all changed nodes.
Produce program for required nodes unconditionally.
Mark all rule updates as validated only if exlicitly asked for it.
Enable recording the dependencies while expanding macro.
Rename/refactor operations in UpdatesRecorder to reflect the intent
of adding the dependencies.
