For use with emailed copies of iPhone IDEAS notes
    Assumes a single Ideas eml file
    Extracts text from email (first in list, only)
        Backs out =20 (and other) escape sequences
        Removes headers and footers
    Splits by newline
    Exports to a text file
        <h2><h2>
        <p>
        whatever text here
        </p>
    
    HEADER_VALUE = h2, but can be changed
    EXPORT_BACKWARDS = True,
        if False order is as written
        
This was overwhelmingly copy/paste from another
    iPhone notes file and took maybe a half hour
