 * This method will find the base node type via the content fragment of the node.
 * Basically, it reads the node type, start, split, join, etc and then assigns
 * the base type to it.  This is necessary because there are cases where the
 * passed in nodeType will no be in the classpath. It should, in theory do
 * the same thing as getNodeTypeForNode.
