#include's use <> everywhere.

Except when including templated files (.txx), Export files (someLibNameExport.h)  and the header file of a classe in its implementation file (.cpp).

I used the folowing script : 

```perl
#!/usr/bin/env perl
##############################################################################################
# Purpose: alwayse use angle brackets to #include, except when including the header of 
# a class in the corresponding .cpp and when including Export headers
# Usage: "includeWithAngleBrackets.pl *.h" 
#   or "find . -name \*.h | xargs includeWithAngleBrackets.pl"

use warnings;
use strict;
use autodie;

use File::Copy qw(move);
use File::Spec ();
use File::Temp ();
use IO::Handle;

sub processSingleFile 
{
    my $filename = shift;
    my ($volume, $dir, $basename) = File::Spec->splitpath($filename); 
    my ($name, $ext) = split(/\./, $basename);
    
    open my $in, '<', $filename;
    my $out = File::Temp->new(DIR => $volume . $dir);
    
    while ( <$in> ) 
    {   
        s/^#include *"(.*)"/#include <$1>/ig 
          if (!m/^#include *"((\Q$name\E(_p)?|.*Export)\.h|.*\.txx)/ig);
        print $out $_;
    }
    $out->flush();
    move($out->filename, $filename);
}

for (@ARGV) 
{
    processSingleFile $_;
}
```
