options.layout: global layout template name, default is undefined.
options.locals: global locals, can be function type, this in the function is toa's context.
options.writeResp: Write template to response body, default is true.

options.base: Everything before a glob (same as tplName) starts, default is ''.
options.delimiter: Character to use with angle brackets for open/close, default is %.
