Simplifying a path

[Ottia Tuota]

I think that here most cases are pathological. But that word "shortcut" was good. I changed the error measuring routine so that it cuts its work short as soon as the error exceeds the allowed value. The running time came down from 41 seconds to 25 seconds in a test case. I really should have realized to do this myself. Thanks for the help.

But the code should be overhauled anyhow. We shall see. Now I think I shall be doing something else for awhile.

The new version is 0.8 in the same place:
