debugging options; thanks Chris for spoting this

* added TheoryArith::preRewrite() to test and demonstrate
the use of pre-rewriting.
* array types and type checking now supported
* array type checking now supported
* theoryOf() dispatching properly to arrays now
* theories now required to implement a (simple) identify()
function that returns a string identifying them for
debugging/user output purposes
* added "builtin" theory to hold all built-in kinds and their
type rules and rewriting (currently only exploding distinct)
* fixed production build failure (regarding NodeSetDepth)
* removed an errant "using namespace std" in util/bitvector.h
(and made associated trivial fixes elsewhere)
* fixes to make unexpected exceptions more verbose in debug builds
* fixes to make multiple, cascading assertion fails simpler
* minor other fixes to comments etc.

expect a little turbulence. This commit will not compile. There will be a second commit that fixes this in a moment. I am delaying a change to avoid svn whining about a conflict.

data into a CDMap. Such a key doesn't disappear from the map on pop,
but rather returns to its "initializing" state, set by
insertAtContextLevelZero(). This can be used for lazy assignment,
among other things, and has been added to support some exploratory
coding by Tim in arithmetic.
* Made internal CDOmap<> copy constructor private (it should always have
been). This is necessary to avoid CxxTest (or others) doing nasty
generic programming things that cause context invariants to be broken.
* Added unit testing for this feature, and in general beef up the unit
testing for CDMap<>.
* src/expr/node_manager.cpp: Better output for unhandled cases in getType().

attribute. There is now a priority queue for selecting the smallest inconsistent basic variable. normal.h has been removed. A large chunk of the registerTerm() stuff has been moved into preregister. The lazy splitting code is now been commented out so that it stops showing up in profiling.

** file-level documentation at the top of the sources. **
This is the "make bugzilla stop bugging me" bugfix commit.
* Remove BackedNodeBuilder<> and collapse NodeBuilder<> hierarchy.
Updated documentation in the file. Resolves bug #99.
* Convenience NodeBuilders (PlusNodeBuilder, OrNodeBuilder, etc.)
moved into a separate file. Partially resolves bug #100.
* Moved isAssociative(Kind) into kind.h (and into the CVC4::kind
namespace) instead of metakind.h (where it was in CVC4::metakind).
This clears up a warning (private #inclusion) from the SMT and SMT2
parsers, and maybe makes more sense anyways, since this is based on
the kind (and not the metakind) of an operator.
* Documentation improvement; doxygen top-level \file gestures, \brief
gestures for files, etc. Changed contrib/update-copyright.pl for
this change, and post-processed to add \brief. Resolves bug #98.
* Removed ExprManager::mkExpr(Kind) and NodeManager::mkNode(Kind).
They no longer made sense. Resolves bug #91.

assignment for slack variables once solving has begun. (They cannot just be 0.) The second has to do with how assignments are backttacked. Assignments are now tracked all of the time, and are frozen once they are known to be consistent, i.e. after a successful updateInconsistentVars(). Also added a fuzz test that shows both of these problems to the regressions.

with that of Node.
* If NodeBuilder<> hasn't yet been assigned a Kind, several member functions
related to children now throw an IllegalArgumentException:
* getNumChildren()
* begin()
* end()
* operator[]
* getChild()
This is because if you later assign the NodeBuilder<> a PARAMETERIZED kind,
the children are "reinterpreted" -- the first being an operator. Interface-wise,
it doesn't make sense to return one thing for nb[0], then later, after setting
the kind, to return another thing for nb[0].
* Fixed unit tests depending on this behavior.
* Added a warning to the testing summary if unit tests didn't run (because this
is likely due to compilation problems, and without a warning it looks kind of
like a test success)
* VERBOSE wasn't exported to the environment for unit test "make check." Fixed.

translation must indeed be a clause (if possible). I've changed the top level CNF conversion to generate clauses, instead of introducing unit clauses for each assertion.
