This module provides a simple way to align a text on the left, right or
center. If left & right are easy to achieve (see 'sprintf()'), i found no
cpan module that achieved a simple text centering. Well, of course, the
Perl6::Form manpage provides it, but it's incredibly slow during startup /
destroy time. And the Text::Reform manpage was segfaulting during destroy
time.

Hence this module, which aims to provide only those 3 methods.
