Integrity check for data structures.

One of the things that can go wrong when implementing a new kernel is that a result data object might be in an invalid state. This can happen because we allow direct access to the underlying data buffers, for efficiency reasons. For instance, a CSRMatrix might contain out-of-bounds column indexes etc. It would be great to add some kind of checkIntegrity function to the interface of Structure, which verifies the internal integrity of the structure and throws an exception if it finds any violations. This method should be implemented by all sub-classes.

This utility would be a helpful addition to our unit test cases. It is not intended to be used in the actual program.
