Scott Sanderson e491ebef53 ENH: Initial support for international pipelines. ... This commit adds initial support for international markets in the Pipeline API via addition of the concept of "domains". Significant changes on this branch include: - Added `zipline.pipeline.domain` and the `Domain` interface. - Added several canonical domain definitions: - GENERIC - US_EQUITIES - CA_EQUITIES - GB_EQUITIES - Added `zipline.country` as a place to define canonical country code names. - Made `PipelineLoader` an interface and added new `domain` parameter to signature of `load_adjusted_array`. - Added a new system for "generic" and "specialized" DataSet and BoundColumn objects. - Added a new system for inferring a domain from a pipeline that contains a mix of generic and non-generic terms. - Reworked the built-in pricing dataset. USEquityPricing dataset is now a specialized version of a generic EquityPricing dataset, and most built-in factors are now implemented in terms of EquityPricing rather than USEquityPricing. - Removed `zipline.data.us_equity_pricing`. - Moved BcolzDailyBar{Reader,Writer} to `zipline.data.bcolz_daily_bars`. - Moved SQLiteAdjustment{Reader,Writer} to `zipline.data.adjustments`. New dependencies added as part of this work: - iso3166 (for canonical country code definitions) - python-interface (for strict interface definitions). See https://github.com/quantopian/zipline/issues/2265 for a full description of the design for domains.		2018-09-10 10:05:39 -05:00
