* @defgroup errorhandling Error Handling
*
* \brief These classes and related functions are used to handle errors and
* unknown events within Cantera.
*
* The general idea is that exceptions are thrown using the common
* base class called CanteraError. Derived types of CanteraError
* characterize what type of error is thrown. A list of all
* of the thrown errors is kept in the Application class.
*
* Any exceptions which are not caught cause a fatal error exit
* from the program.
*
* Below is an example of how to catch errors that throw the CanteraError class.
* In general, all Cantera C++ programs will have this basic structure.
*
* \include edemo.cpp
*
* The function showErrors() will print out the fatal error
* condition to standard output.
*
* A group of defines may be used during debugging to assert
* conditions which should be true. These are named AssertTrace(),
* AssertThrow(), and AssertThrowMsg(). Examples of their usage is
* given below.
*
* @code
* AssertTrace(p == OneAtm);
* AssertThrow(p == OneAtm, "Kinetics::update");
* AssertThrowMsg(p == OneAtm, "Kinetics::update",
* "Algorithm limited to atmospheric pressure");
* @endcode
*
* Their first argument is a boolean. If the boolean is not true, a
* CanteraError is thrown, with descriptive information indicating
* where the error occured. These functions may be eliminated from
* the source code, if the -DNDEBUG option is specified to the
* compiler.
*
