+    <dt>
+    <a name = "pl.OrderedMap:_init"></a>
+    <strong>pl.OrderedMap:_init (t)</strong>
+    </dt>
+    <dd>
+    construct an OrderedMap.
+ Will throw an error if the argument is bad.
+
+
+    <h3>Parameters:</h3>
+    <ul>
+        <li><span class="parameter">t</span>
+         optional initialization table, same as for <a href="../classes/pl.OrderedMap.html#pl.OrderedMap:update">OrderedMap:update</a>

+    <dt>
+    <a name = "pl.OrderedMap:update"></a>
+    <strong>pl.OrderedMap:update (t)</strong>
+    </dt>
+    <dd>
+    update an OrderedMap using a table.
+ If the table is itself an OrderedMap, then its entries will be appended.
+ if it s a table of the form <code>{{key1=val1},{key2=val2},...}</code> these will be appended.</p>
+
+<p> Otherwise, it is assumed to be a map-like table, and order of extra entries is arbitrary.
+
+
+    <h3>Parameters:</h3>
+    <ul>
+        <li><span class="parameter">t</span>
+            <span class="types"><span class="type">tab</span></span>
+         a table.

+    <a name = "pl.OrderedMap:set"></a>
+    <strong>pl.OrderedMap:set (key, val)</strong>
+    </dt>
+    <dd>
+    set the key's value.    This key will be appended at the end of the map.</p>
+
+<p> If the value is nil, then the key is removed.
+
+
+    <h3>Parameters:</h3>
+    <ul>
+        <li><span class="parameter">key</span>
+         the key
+        </li>
+        <li><span class="parameter">val</span>

+    <dd>
+    insert a key/value pair before a given position.
+ Note: if the map already contains the key, then this effectively
+ moves the item to the new position by first removing at the old position.
+ Has no effect if the key does not exist and val is nil
+
