MultiVectorBase implementation to provide default implementations for as many other functions in MultiVectorBase interface the as is reasonable.
Notes to subclass developers
Only three function overrides are required in order to create a concrete MultiVectorBase subclass: range(), domain() and the non-const version of col(). All of the other functions have default implementations. However, a good implementation will provide optimized overrides of at least the functions apply() and applyTranspose(). The non-const versions of subView() should be overridden if subviews are important. The default implementation will not achieve near-optimal performance in many cases.

| ) | const [virtual] |
This implementation is based on the vector operation VectorBase::acquireDetachedView() called on the non-changeable vector objects returned from col(). Note that the footprint of the reduction object (both internal and external state) will be O(rowRng.size()*colRng.size()). For serial applications this is fairly reasonable and will not be a major performance penalty. For parallel applications, however, this is a terrible implementation and must be overridden if rowRng.size() is large at all. Although, this function should not even be used in cases where the multi-vector is very large. If a subclass does override this function, it must also override releaseDetachedView() which has an implementation which is a companion to this function's implementation.

This implementation uses the vector space to create a new multi-vector object and then uses a transformation operator to assign the vector elements. A subclass should only override this function if it can do something more sophisticated (i.e. lazy evaluation) but in general, this is not needed.
