fillInDefaultOptions
created PolySystem type
made "track" use PolySystem
modified trackHomotopy and preSLPs to use higher precision arithmetic
newton implemented as a separate method (for square, under- and overdetermined systems)
new deflation routines; numericalRank (somewhat) fixed; isFullNumericalRank
