/**
 * Takes care of reading in xml formatted data from a file.  This could/should
 * be made more arbitrary in the future so that we can read the data from any
 * source.  This is actually made quite simple already since all data read in
 * is handled by one single helper function and then palced into a FlexBuf for
 * easy access by the other functions.  The FlexBuf also allows for block
 * reading from disk, which improves speed by a noticable amount.
 * <br>
 * There are also some extra features implemented that allow you to break the
 * standard XML reader specs and eliminate leading and trailing whitespace in
 * all read content.  This is useful in situations where you allow additional
 * whitespace in the files to make them easily human readable.  The resturned
 * content will be NULL in sitautions where all content between nodes was
 * stripped.
