[Insight-developers] Installation under Linux

[Bill Hoffman]

There would be quite a few files in that directory, and with all
the extra utilities that ITK uses, and the .txx files, it could become
a problem, and quite a mess.

Another alternative, would be to change the coding conventions slightly.

Instead of 
#include <itkObject.h>
#include <itkAcosImageFilter.h>

it would be:

#include <Common/itkObject.h>
#include <BasicFilters/itkAcosImageFilter.h>

This would allow us to have only one -I path, but leave all
the files in separate directories.   Vnl already takes this
approach.

In addition to avoiding directories with thousands of files, it
provides extra documentation to users.    Users would know
where to find classes used in a file just by looking at the
include directives.
