/**
* Loads model files from all bundles in the classpath.<br>
* Caveat: For compatibility with Apple's RuleEditor, this method automatically adds the
* ".d2wmodel" extension to all names (with or without extension that you pass into this method.
* That is we use "double extensions": the one specified as an argument plus the ".d2wmodel" one.
* To the caller this is mostly transparent. Remember not to pass the extension or names including
* the extension ".d2wmodel" as arguments. Remember to name your files including the ".d2wmodel"
* extension.
*
* @param extension file name extension to look for
* @param includeNames explicit list of file names (w/o extension) to accept, accepts all if null.
* @param excludeNames explicit list of file names (w/o extension) to refuse, accepts all if null
* @param includesFiles explicit list of file names (with extension) to accept in addition to
* otherwise accepted files
