<overview>
<p>This metric measures the maximum nesting depth of statements. When statements are nested too 
deeply in the code they become difficult to understand. This is because understanding a line that 
is deeply nested requires an understanding of the context of that line.</p>

</overview>
<recommendation>
<p>The best way to address this problem is to extract more deeply nested parts of the code into their own logical 
methods.</p>

</recommendation>
<example>
<p>This method has a nesting depth of 4.</p>
<sample src="StatementNestingDepth.cs" />

</example>
<section title="Fixed by Extraction">
<p>This code is easier to read because the part that prints every character in the string along 
with its character code has been extracted to a separate method.</p>
<sample src="StatementNestingDepthFix.cs" />
