This module implements a generic preprocessing facility. It runs a given strategy on the input and retrieves the simplified formula using the facilities of the Manager class. This process is iterated until a fix point is reached – no further simplification was done by the strategy – or a predefined number of iterations was performed. The resulting simplified formula is then forwarded to the backend.

The strategy should be a linear sequence of preprocessing modules, as passing simplified formulas back to the caller is not possible in a meaningful way for general Module classes.
