<h4><a name="elementstring"></a>What are Elementstrings?</h4>

<p>Elementstrings are a special sort of short (and dynamic)
stringarrays. Every array-entry was divided with a separator from
the next entry. For example, the elementstring
&quot;zero|one|two|three&quot; has four elemententrys. With this
class you can easyly get, set or find a specified element. You
don't have to specify the size of the 'array', because it's only
one string. The entries can be strings, chars, doubles, ints or
bools. If you set an entry, the numbers are converted into
strings and if you get one, it was back converted to the
specified type. Normaly the separator is '|', but it's possible
to use every other character.</p>
