Create navigation content for a file with relative path a/b/c/bob.md and the specification $specs and default templates:

$specs is defined like so:

$specs = @(
    @{ "<img width='90%' src='logo.png' />" = "README.md" },
    @{ "README" = "" },
    @{ "Home" = "README.md" },
    @{ "---" = "" }
)

Output:

<button class="navitem">
   <a href="../../../README.html">
      <img width='90%' src='../../../logo.png' />
   </a>
</button>
<div class="navlabel">README</div>
<button class="navitem">
   <a href="../../../README.html">Home</a>
</button>
