* add test for validate multi reward periods * tidy up: combine files * don't accumulate global indexes containing zeros Previously if the time since last block was 0, indexes were added containing 0s. Now leave them out. Missing is assumed to be 0. * move state independent test to types folder * clarify reward source concept to "source shares" - rename variables and update doc comments - extract method from swap accumulation * tidy up and expand swap accumulation unit tests * rename swap test file to match others * update swap pool id format in tests * refactor borrow accumulation, use new accumulator * refactor supply accumulation, use new accumulator * refactor delegator accumulation, use accumulator * refactor usdx accumulation, use new accumulator * fix types const * remove unsed methods * more usdx minting param validation. Protect against the rewards per second denom changing. It should always be "ukava". * add safety check in InitGenesis It prevents huge accumulations on the first block by limiting all previous accumulation times to be within one year of genesis * add todo for adding swp token distirbution info
