correction to scripts b0.955

[dan_fabrizio]

Hi All,

The TimingAnalyzer stores 3 times for each edge.

The first is the time at the beginning of the edge transition.
The second is the the time of the edge usually set to the half way
point of the edge.
The third is the time at the end of the edge transition.

It also saves 2 sets of these points. One set for the minimum edge
times,
and one set for the maximum edge times for margins and delays.

The following methods where changed in b0.955

getPt1() should be changed to getPt1Min()
getPt2() should be changed to getPt2Min()
getPt3() should be changed to getPt3Min()

Some of the included scripts use getPt2() so they need to be changed
to getPt2Min() .

Let me know if you have any trouble fixing the scripts.
Dan
