#3 Parameter Exporters

[KOBAYASI Hiroaki]

Each template should automatically 'import' following vars:
------------
for cgi, $CGI
for mod_perl, $REQ

for both, $PAGE, $SYSTEM(=~ error handler)
------------

But, these should be overridable/augmentable in '.yattrc'!

Also, importing some nice modules/funcs (ie
List::Utils) is nice.
