SSV formatter

The SSV formatter sums all dimensions in results of database queries to a single value and returns a list of such values showing how it changes through time.

It supports the following formats:

format	content type	description
ssv	text/plain	a space separated list of values
ssvcomma	text/plain	a comma separated list of values
array	application/json	a JSON array

The SSV formatter respects the following API &options=:

option	supported	description
nonzero	yes	to return only the dimensions that have at least a non-zero value
flip	yes	to return the numbers older to newer (the default is newer to older)
percent	yes	to replace all values with their percentage over the row total
abs	yes	to turn all values positive, before using them
min2max	yes	to return the delta from the minimum value to the maximum value (across dimensions)
