amended comment
added stubs for pdf generation
renamed text to ctp
created a complicated crab-spider structure to allow the background processing shell to pass a closure into the job model which allows the background processor tasks to generate latex by rendering a view in a headless instance of the controller. it works.
improved separation of pdf stuff in job model (now all id based only and all pdf data logic in own methods) and tweaked _makeJobTmpDir to return dir if its already been created
