 * checking for the dimensions of a wave function or an operator or a matrix applied along a single dimension occurs again and again. It would be useful to have such checking at hand.
 * There is no possibility to easily form a direct product. Such tensor extensions would be nice.
+* an internally used ThrowOnNull template function that takes a shared_ptr&lt;T&gt; and a message and throws a NullPointerException if the ptr is null. Nice shortcut for the code; could be part of wp_exceptions.hpp
+* merge Representation::hasWavefunctionShape() and Representation::hasOperatorShape() to hasStateShape or so for easier error checking. Maybe a utility function would also make sense here.
