This patch lays the groundwork for a compute engine designed to facilitate construction of factor-based universe screening and portfolio allocation. It contains: A new module, `zipline.modelling`, containing entities that can be used to express computations as dependency graphs. Each node in such a graph is an instance of the base `Term` class, defined in `zipline.modelling.term`. Dependency graphs are executed by instances of `FFCEngine`, defined in `zipline.modelling.engine`. A new module, `zipline.data.ffc`, containing loaders and dataset definitions for inputs to the modelling API. New `TradingAlgorithm` api methods: `add_factor`, and `add_filter`. These methods can only be called from `initialize`, and are used to inform the algorithm that each day it should compute the given terms. Computed factor results are made available through a new attribute of the `data` object in `before_trading_start` and `handle_data`. Computed filter results control which assets are available in the factor matrix on each day.
