an answer to "Do compilation?",
then Qubiter will look for a file named "MATNAME.in". In other words, it
will look for a file whose name is the string in line 2 plus the suffix ".in".
Qubiter expects to find in this file the entries of the unitary matrix

<P>
If the user enters 1 into line 6 as an answer to "Do decompilation?", then
Qubiter will look for a file named "MATNAME-engl.out
