Change the Fiji temp Folder (by passing JVM arguments)

Why? For example if you run Fiji headless on a cluster and you would like it to use a fast local folder instead of a network drive.

This page tells you how you can pass on JVM arguments to Fiji upon start: http://fiji.sc/Java_Options

One can specify the “temp” directory using the following command:

$ fiji -Djava.io.tmpdir=~/tmp -- &

Double dash at the end is required to specify that the given argument is for Java.
