Help documenting 3 new functions for CI 1.5.5

[eluser]Derek Allard[/eluser]
Hey all.

We're ramping up for CI 1.5.5, and just adding a bunch of things in. If you're anxiously looking forward to the release and want to help, I could use a hand on something. The string helper (in the SVN) has 3 new functions: strip_quotes(), quotes_to_entities(), reduce_multiples().

The help I need is
1) Test them, just make sure they behave
2) I need a hand writing the documentation for these. If someone wanted to take a stab at writing the user_guide writeup for them, I'd greatly appreciate it. Here's a template

Code:

<h2>strip_quotes()</h2>
<p>Explanation of what it does. Example:</p>
<code>example code here, as simple as possible.</code>
<p>Any summary info goes here, including options, and more code examples if needed.
Code examples go in <code> tags please.</p>
