/**
 * This method has been deprecated use the Java Path relativize method instead.
 * Strips the base directory out of a file path to make a relative file path. If the file doesn't contain the base path the original path is returned.
 * @param basePath The base directory path to remove from the file path.
 * @param toRelativize The file to be made relative.
 * @return The relative file path created by removing the base directory. Returns null if the file to relative is null.
