* Reads the contents of a named sub element within a given element, and attempts to parse the contents as a Java

* <p/>
* E.g., if you have a {@link Element} which represents the following XML snippet:
* <p/>
* <pre>
* <props>
* my.attrib.1 = blah
* my.attrib.2 = blahblah
* </props>
* <pre>

* The following results could be expected:

* <pre>
* Properties p = readPropertiesContents(element, "props");
* p.getProperty("my.attrib.1"); // blah
* p.getProperty("my.attrib.2"); // blahblah
* </pre>
* None of the parameters should be null - otherwise the method may throw a NullPointerException.
*
* @param element - element to search through.
* @param elementName - name of the element to find within the element passed in
* @return a {@link Properties} object, never null.
* @throws IOException if unable to parse the contents of the element
