Add Algorithm::setExecuted(false) to Algorithm

Throw an exception when fail to make volume

Move SNS to use ONCAT for finding files

There is a bug that the algorithm is somehow already declared
itself executed before actually running the `exec()` method. This just
sets it to false just before the call, then it is set to true if no
exception is thrown.

Previously the integration volume would be quietly undefined. This makes
it much more obvious to the user when something goes wrong. The
underlying issue is in the numerics of determining what is inside the
shape.
