   Base class for portfolio construction.

   This class defines the interface for all portfolio construction strategies.

   The `__call__` method is called by the framework to construct the portfolio.
   It is expected to clear the current allocations and add the new allocations.

   The `run` method is called by `__call__` to perform the portfolio construction.
   It must be implemented by subclasses to return an iterable of `Allocation` objects.


   .. py:method:: __call__(context: modular_trader.context.Context, signals: modular_trader.signal.SignalCollection) -> Any


   .. py:method:: run(context: modular_trader.context.Context, signals: modular_trader.signal.SignalCollection) -> collections.abc.Iterable[modular_trader.allocation.Allocation]
      :abstractmethod:


      Must be implemented by subclasses.

      Called by `__call__` to perform portfolio construction.
