DOC: Removed Doxygen \example tags for Tests.

Several \example tags were using Test files are targets. This was producing
warnings in Doxygen, since the path to the actual files was not propely
specified. Given that the Test files themselves are not good examples for
users, here we opt for removing the references altogether.

COMP: Fix warnings in matrix division by scalar.

At compilation time we were observing the following warning in Debian 7
with gcc 4.7:

itkFixedArray.h:197:82: warning: array subscript is above array bounds

A binary disection of the code lead to identifying the division by a scalar of
a VariableSizeMatrix as the culprit.

Expanding the division expression using two nested for loops resolves the
warning.

It is still unclear why a method in the itkVariableSizeMatrix class would
trigger a warning in the itkFixedArray class.
