An updating ascii data file is re-read with every update


Add suitable debug statements to the ascii datasource code so that you are
advised of the samples that are being read from Kst
Create an ascii data file with a single vector that adds a new item every
second in time
Start Kst and create a plot with this vector in, where the vector is in
read-to-end mode

On every update the vector is re-read in its entirety

Only the newly added samples are read
