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