svn ci -m "meaningful message"

Warning:
-- do not use the same names as in NAG

Point:
-- to convert to the new Point type use constructor "point" applied to the old data structure, which is List.
-- if p is Point then
--   coordinates p
--   peek p -- displays the HashTable
--   one can address particular fields: p.SolutionStatus

To do:
-- delete refineSoln
-- extend mixedVolume with StartSystem => true option
-- interface Pieri, LR homotopies
-- make sure trackPaths, refineSolutions, monodromyBreakup, cascade WORK
-- add witnessSetIntersect
-- write tests
