Short summary: By default NODEID is appeneded, just continue doing what you
were, just don't add the _$$ at the end.
Long summary:
Before this commit there were four (yes!) ways to specify the names for new
skolems, which result in names as given below
1) mkSkolem("name", ..., SKOLEM_FLAG_DEFAULT) -> "name_NODEID"
2) mkSkolem("name", ..., SKOLEM_EXACT_NAME) -> "name"
3) mkSkolem("name_$$", ..., SKOLEM_FLAG_DEFAULT) -> "name_NODEID"
4) mkSkolem("na_$$_me", ..., SKOLEM_FLAG_DEFAULT) -> "na_NODEID_me"
After this commit, only 1) and 2) stay.
90% usage is of 1) or 3), which results in exact same behavior (and
looking at the source code it doesn't look like everyone realized that
the _$$ is just redundant).
Almost no one used 4), which is the only reason to even have $$. Post this
commit if you really want a number in the middle, manually construct the
name and use the SKOLEM_EXACT_NAME flag.

just the header comments at the top, though. Don't update to this rev if
you don't have time for a complete rebuild, and exclude this rev if you
want to see what's new across a range of commits.

cleaned up model code, TheoryModel::getValue is now const.
|

meeting last week. The SmtEngine now subscribes to NodeManager events,
does appropriate dumping of variable declarations, and notifies the Model
class.
The way to create a skolem is now:
nodeManager->mkSkolem("myvar_$$", TypeNode, "is a variable created by the theory of Foo")
The first argument is the name of the skolem, and the (optional) "$$" is a
placeholder for the node id (to get a unique name). Without a "$$", a "_$$"
is automatically appended to the given name.
The second argument is the type.
The (optional, but recommended) third argument is a comment, used by the
dump infrastructure to indicate what the variable is for / who owns it.
An optional fourth argument (not shown) allows you to specify flags that
control the behavior (e.g., don't do notification, and/or don't make a
unique name). Look at the documentation for details on these.
In particular, the above means you can't just do a mkSkolem(boolType) for
example---you have to specify a name and (hopefully also,
but it's optional) a comment. This leads to easier debugging than the
anonymous skolems before, since we'll be able to track where the skolems
came from.
Much of the Model and Dump stuff, as well as some Command stuff, is cleaned up
by this commit. Some remains to be cleaned up.

collectModelInfo with fullModel argument, most theory-specific implementation out of the model class, model printer relegated to printer classes. Also updates to finite mode finding, modifications to datatypes making them compatible with theory combination, support for theory-specific handling of user attributes, refactoring of uf models
