gordon chung 6ef079953e add delta transfomer support ... this patch adds support for a delta transformer. the transformer's only functionality is to calculate the delta between current sample and previous sample. conditions: - it will disregard any out of order samples - a growth_only param is available to capture only positive deltas - supports renaming to a new meter name using same schema as other transformers. using this transformer, we also create a cpu.delta meter which will enable another view of cpu meter. this delta meter will allow for (relatively) accurate cputime calculations and will cope with cputime resets.
