Implementation of Wilkinson formulas

Formulaic is a high-performance implementation of Wilkinson formulas for Python. It provides: * high-performance dataframe to model-matrix conversions. * support for reusing the encoding choices made during conversion of one data-set on other datasets. * extensible formula parsing. * extensible data input/output plugins, with implementations for: * input: * pandas.DataFrame * pyarrow.Table * output: * pandas.DataFrame * numpy.ndarray * scipy.sparse.CSCMatrix * support for symbolic differentiation of formulas (and hence model matrices).
