When an analysis is completed, the Report tab in 5Spice is listed with values of the variables for different time points.
Save the data in the Report tab of the 5Spice program in a file called "data.txt".
This script parses that text file and imports the variables into workspace.
Read the comments inside the script for further usage.
(The file name need not actually be data.txt, it is assumed if no input args are given.)
