Logtalk

Corrected the description of the internal predicate '$lgt_compile_aux_clauses'/1.

Added an "attvarsp" experimental example of using attributed variables within Logtalk parametric objects and parametric categories (requires an experimental branch of SWI-Prolog).

Removed from the "attvars" example the limited support for parametric objects and parametric categories.

Updated the "integration" example unit tests in order to avoid some false failures when using SWI-Prolog.

Updated the "attvars" example in order to provide limited support for using attributed variables within parametric objects and parametric categories.

Reverted changes on the Logtalk compiler that forced public/1, protoected/1, private/, and coinductive/1 directives to appear in a source file before any calls to the referenced predicates.

Updated the "expansion" example with more sample code on how to combine term- and goal-expansion definitions from different hooks objects.

Added information on entity declared operators to the XML documenting files. Updated the text, PDF, and (X)HTML conversion scripts to print out operator information.

Minor code formatting updated to some examples to better match current practice.

Updated the "profilers" example with preliminary support for the changes to execution profiling in the forthcoming SICStus Prolog 4.2 version.
