[Insight-developers] compile erros under linux

[Jisung Kim]

The following statement came from the ANIS C++ 
"December 1996 Working Paper"

"There  is  no semantic difference between class and
typename in a template-parameter."  

If I understand it correctly, even though you used the
typename at the template parameter declaration, you 
should you typename every time you use types from the
template paramter (typename T::AVariableType)
