Just a few things re-arranged, moved the new taf/xml systems to the inprogress
directory, and moved the old xml system in, so it will require heavy changes.

14 | * is handled by one single helper function and then palced into a FlexBuf for | ||
15 | * easy access by the other functions. The FlexBuf also allows for block | ||
16 | * reading from disk, which improves speed by a noticable amount. | ||

18 | * There are also some extra features implemented that allow you to break the | ||
19 | * standard XML reader specs and eliminate leading and trailing whitespace in | ||
20 | * all read content. This is useful in situations where you allow additional | ||
21 | * whitespace in the files to make them easily human readable. The resturned | ||
22 | * content will be NULL in sitautions where all content between nodes was | ||
23 | * stripped. | ||
