Provide more guidance for understanding examples, update .travis.yml.
This commit adds an `example/README.md` file with a little bit of
guidance for running the examples themselves. This is helpful because
the examples all rely on the presence of a `phpseclib` installation
available to the PHP interpreter, and while there is a `composer.json`
file to this effect, none of the examples included the Composer
`autoload.php` file.

This commit makes no modifications to the example code itself, but does
`include_once()` the Composer autoload script so that `phpseclib` loads
and avoids causing a fatal error when a new user attempts to run the
examples to learn how to use the library.

This commit also updates the Travis `before_script` build script, dropping
the `--dev` argument to the `composer install` command. Current versions
of Composer emit a deprecation notice when `--dev` is passed.
