I have added publication data to some more of the references here

]]>I was about to add this reference

- Steven Krantz, Harold Parks,
*Geometric integration theory*(pdf)

to a new entry *geometric integration theory* when I discovered that there was already *geometric measure theory*.

I have now added redirects and added the reference.

]]>New entry geometric measure theory with idea and bibliography, new stub rectifiable set for now just pointing to wikipedia article and a new section in the entry measure theory dwelling on subfields. Could be done better.
