<hr><a name="_details"></a><h2>Detailed Description</h2>
Store configuration options in an XML tree.
<p>
<dl compact><dt><b>Author:</b></dt><dd>Nemosoft Unv.</dd></dl>
With this class configuration options for applications can be easily stored and retrieved in XML format. Rather than wading through a complex XML tree, this class lets you store a simple list of options and references their values by their name.<p>
This class won't do recursive storage or grouping. It's a simple 1-to-1 list. For 90% of the cases, that is enough.<p>
The class should be initialized with a list of variable names and their defaults using <a class="el" href="class_c_options_x_m_l.html#b1">DeclareVariable</a> . Trying to set a variable name that isn't in the list will be ignored; getting a variable that isn't there will return a null variable.
