Summary Report stratification is not measure specific nor including all patients

[mholck]

Stepping through the code when evaluating a summary measure report it looks like since the type is POPULATION it queries all patients but is only getting back the first 20 patients and is not handling the paging to get the remaining ones. Then it is stratifying the SDEs for those 20 patients regardless if they are in any of the measure populations. In QRDA III it would stratify each population by the SDEs but if the intent is just to stratify for the measure it should at least be using the Initial Population to perform this stratification and not just all patients.
