// Class : Notify
// Description : An object that handles general error reporting to the
// user. It contains a pointer to an ostream, initially
// cerr, which can be reset at will to point to
// different output devices, according to the needs of
// the application. All output generated within Panda
// should vector through the Notify ostream.
//
// This also includes a collection of Categories and
// Severities, which may be independently enabled or
// disabled, so that error messages may be squelched or
// respected according to the wishes of the user.

// This defines the symbol nout in the same way that cerr and cout are
// defined, for compactness of C++ code that uses Notify in its
// simplest form. Maybe it's a good idea to define this symbol and
// maybe it's not, but it does seem that "nout" isn't likely to
// collide with any other name.

// Here are a couple of assert-type functions. These are designed to
// avoid simply dumping core, since that's quite troublesome when the
// programmer is working in a higher-level environment that is calling
// into the C++ layer.
// nassertr() is intended to be used in functions that have return
// values; it returns the indicated value if the assertion fails.
// nassertv() is intended to be used in functions that do not have
// return values; it simply returns if the assertion fails.
// nassertd() does not return from the function, but instead executes
// the following block of code (like an if statement) if the assertion
// fails.
// nassertr_always() and nassertv_always() are like nassertr() and
// nassertv(), except that they will not get completely compiled out
// if NDEBUG is set. Instead, they will quietly return from the
// function. These macros are appropriate, for instance, for sanity
// checking user input parameters, where optimal performance is not
// paramount.
