StartNotFixture

The actor (start class) has to be a Fixture subclass

There were two problems with this: first, java.awt.Point is not a Python class, and second the exceptions were in the wrong place. I changed java.awt.Point to fit.Counts.

fitLib.FixtureFixture
fixture	fit.ActionFixture
-e	start	fit.Counts
-e	enter	x	12

Notice how subsequent rows of the table just above are interpreted even though the start failed. Similarly for the table below, where ActionFixture continues even though there is a problem (exception) with a row.

What subsequent rows? The comment is right, however.
