Maya Tydykov d0cb5bd513 ENH: add extension to AssetFinder that caches all equities in memory and uses that cache in lookup_symbol. 2015-11-12 11:02:26 -05:00

Stewart Douglasandjfkirk 746f70a133 ENH: Create AssetDBWriter class 
The AssetDBWriter class and its subclasses will
ultimately be responsible for creating the SQLite
database tables and writing data to these tables.

In the longer term AssetDBWriter and AssetFinder will
be decoupled, sharing only an SQLite connection.
However, for backward compatibility reasons this has
not yet been fully implemented.

Modify tests since AssetFinder no longer has a
metadata_cache attribute.
