Description:
------------
I just installed the markdown pecl package with:

sudo pecl install markdown channel://pecl.php.net/markdown-0.1.0

I tried to use the functions as described on the mkd.php file on the Examples directory.

Reproduce code:
---------------
<?php

error_reporting(E_ALL | E_STRICT);
echo Markdown::parseToString('a simple "string" to parse');



Expected result:
----------------
To run the string without problems, but I get the following error:

Strict Standards: Non-static method Markdown::parseToString() should not be called statically in /home/jackbravo/work/mark.php  on line 4

a simple ?string? to parse

Actual result:
--------------
a simple ?string? to parse
