remove .DS_Store
condense xml header, remove unused namespaces
get rid of empty lines
remove space padding
identation
remove indentation on php

This allows the xml output to indent properly
express subject tags in loop rather than other way around
fix output when there are no tags

This if statement is unnecessary
more cleanup in subject expression
oops, fix xml header

now almost possible to make a valid record
move pbcore elements into foreach loops

better handling of empty fields or recurring fields
allow possibility of valid pbcore output

still many issues, output is invalid if uses HTML or other invalid text
within an element. The instantiaitonIdentifier is wrong and needs to be
fixed. Also invalid output is possible if the cataloger doesn't meet
pbcore minimums.
move transcription from annotation to description
delete another pesky .DS_Store
