abstract interface for an input stream

An input stream provides methods to read the basic C++ types from the stream. Based on this information, more complicated types can be read from the stream by using these basic input operations.

Normally, the input methods of the stream are not used directly, but the operator >> ist used to read information from the stream. This operator should also be overloaded for all types that should be readable.

Unlike STL streams, dune-fem input streams throw a StreamError exception when a reading operation fails. Since the program is automatically aborted, if the exception is not caught, careless programming will not result in uninitialized objects. If the user catches the exception, he may not assume the object, that should be read, to be in a defined or even useful state.
