* working on formatters
* working on jsonwrapper
* finally, it compiles...
* 1st run without crashes
* query planer working

* ml should accept NULL response from rrd2rrdr()
* number formatting fixes

* support mc parallel queries
* formatting and cleanup
* added rrd2rrdr_legacy() as a simplified interface to run a query
* make sure rrdset_find_natural_update_every_for_timeframe() returns a value
* make signed comparisons
* weights endpoint using rrdcontexts
* fix for legacy db modes and cleanup
* fix for chart_ids and remove AR chart from weights endpoint
* Ignore command if not initialized yet
