RecursionError when trying to print/debug Track objects

[sglvladi]

When trying to print StoneSoup objects that recursively contain a large number of other objects (e.g. Tracks), or debugging scripts that contain such objects, a RecursionError is thrown, e.g.:

RecursionError: maximum recursion depth exceeded while calling a Python object

This seems to happen because of a recursive call to the BaseRepr.whitespace_remove() method (see here).

A script that demonstrates this error can be found here.
