The remove function is for clearing up temporary files after
tests have finished, and for making sure that no instance of a file that
a test is supposed to create already exists before the test is made.
Typical usage is this:-
f=1test
s=s.$f
p=p.$f
remove $f $s $p
The remove function is defined as:-
remove () { rm -rf $* || miscarry Could not remove $* ; }
