2			* \file
3			* \brief Defines the different types of exceptions that 2geom can throw.
4			*
5			* There are two main exception classes: LogicalError and RangeError.
6			* Logical errors are 2geom faults/bugs; RangeErrors are 'user' faults,
7			* e.g. invalid arguments to lib2geom methods.
8			* This way, the 'user' can distinguish between groups of exceptions
9			* ('user' is the coder that uses lib2geom)
10			*
11			* Several macro's are defined for easily throwing exceptions
12			* (e.g. THROW_CONTINUITYERROR).
