pseudoWitnessSet(...,Software=>...) -- specify software for homotopy continuation

This option specifies the software used for polynomial homotopy continuation (used for path tracking) and numerical irreducible decompositions (used for sampling points). The default value is M2engine (native to $Macaulay2$). Other possible values are Bertini and PHCpack (only if the user has these packages installed).
