function Builder::reducePaths

Reduces the paths by cutting the longest common start path.

For instance,

<code> Array ( [/home/sb/Money/Money.php] => Array ( ... )

[/home/sb/Money/MoneyBag.php] => Array ( ... ) ) </code>

is reduced to

<code> Array ( [Money.php] => Array ( ... )

[MoneyBag.php] => Array ( ... ) ) </code>
