Support for ~ home dir, %username% and %homedrive% in paths on the FileBasedSimulationData module
fixed where tabs and spaces were mixed for indenting

Looks like it used tabs when I added the "In directory paths you can use
~ for home directory, %username% to put your user name in the path. On
Windows, you can use %homedrive% in place of your drive letter(Like if
you stored your backups already on an external hard drive letter, X for
example vs. C main drive)." note.
