o expand usage comments; add cut&paste items for bozo's like me
o add things i want to TODO list o add Record entry to each event which back-maps to the line # in the ktr file; useful for finding local context when the ktr file has lots of items that schedgraph doesn't grok o add missing KTR_SCHED event handlers o expose Counter max value through a ymax method for widget building o show timestamps in records rejected 'cuz time goes backwards
