For some use cases, it would be nice to have patsy code a design matrix as if it were going to include an intercept (so e.g. it would exclude some categorical levels), but then not include the intercept. See #80 for details.
This pull request adds an
implicit_interceptparameter to some of the public functions (dmatrix,dmatrices,incr_dbuilder,incr_dbuilders, anddesign_matrix_builders). When set toTrue, it codes the matrix as if an intercept were included but doesn't actually include the intercept.
