of processTemplate, there is a call to $self->get which adds all the asset
properties to the list of template variables. Sometimes they duplicate
entries in the www_ method (like view). Sometimes they're not interesting,
like templateId, but they're still valid template variables.
I'm going to start a new template variable entry for each asset that
will just contain those variables. Any www_ method calling processTemplate
can then include them via ISA into their list of template variables.
