Stewart Douglas 501fd58fdf ENH: Replace update_asset_finder with write_data
The write_data methods invokes the relevant AssetDBWriter subclass
to write data to the database. update_asset_finder is no longer
a relevant method since the AssetFinder is strictly a reader class.

Stewart Douglas 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.

Stewart Douglas c2159d429b ENH: Allow user to set the symbol lookup date
Previously symbols were resolved to sids based on the end of
simulation date. This commit allows the user to specify the
date for which resolution will take place using a new
set_symbol_lookup_date() API method.

If the user does not use this method the lookup date will
default back to the simulation end date.

Scott Sanderson 6e8a4b8144 ENH: Improvements to rank().
- Add an `ascending=True` keyword to `rank()`.

- Add `top(N)` and `bottom(N)` methods to Factor.  These return Filters
  that pass the top and bottom N elements each day.

- Add a slightly faster path for rank(method='ordinal').  I had
  originally thought the fast path was 2-3x faster because I had my
  benchmark data axes flipped.  The actual speedup is only 5-10%, which
  means it probably wasn't worth the effort to Cythonize...but we have a
  slightly faster version now so we might as well use it.

- Refactor test_filter and test_factor to make it easier to implement
  and test transformations on factors.  These tests now subclass
  BaseFFCTestCase, which provides facilities for passing a dict of terms
  and an "initial_workspace", the values for which are used by
  SimpleFFCEngine rather than needing to manually manage the inputs and
  outputs of each term.
