Adds two smarty plugins: 'exp_include' includes a template (file) based on current framework, it can pass an alternate (else) template, (assign) output to a variable, or pass other variables {exp_include file=show else=noshow assign=tempvar anothervar=1}; 'serialize' can disassemble an assoc array for input into the 'assoc_array' block plugin {serialize var=$myarray}
