XSB Src (SVN)-old

Added test for forest view.

A number of changes to extend forest logging to handle negation.

Added support for missing ISO Prolog built-in predicate halt/1.

Added catch to be able to recover from pre-processor errors.

Added decls for call/i (for i>1)

Changed some index defaults,

and added a cdf_flag (implicit_isa) to turn off isa-check for product
data types. With this on, an unindexed call to isa_ext is generated,
which can be very expensive, and unless an application needs full
(well, fuller) isa through product-types, one would rather avoid this
expense. This flag allows that.

Added unindexed profiling.

Changed int type and added cast to quiet compiler.

Added documentation on profiling lack of indexing.

Fixed typo
