/**
* 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.
