<div class="textblock"><p>Main dialog class for the musrStep application. </p>
<p>This class implements the main user interface for viewing and modifying fit parameter step sizes in muSR msr-files. It provides:</p><ul>
<li>A table view displaying all fit parameters with their values and step sizes</li>
<li>Selection mechanisms for choosing which parameters to modify</li>
<li>Automatic and manual step size adjustment options</li>
<li>File I/O for reading and writing msr-files</li>
</ul>
<p>The automatic step size adjustment uses a lookup table based on common muSR parameter naming conventions to determine appropriate step sizes.</p>
