Introduce and explain user-defined functions with functions.xqm

Write, test, and integrate the hoax:round-geo() function

notes on file choices and conventions

• What are the differences among .xq, .xql, .xquery, and .xqm?

• Should we change our file naming conventions? (possibly yes)
  REF: Pg 123 in XQuery for Humanists, use xq for main modules, xqm for library modules
  REF: Eric and adam: roman num 13, use xq for main modules, xqm for library modules
  REF: Priscilla: pg 206, gives example of library that uses .xqm, but no discussion of file names
  REF: TEI Publisher: uses .xql for most things that aren’t explicitly function libraries

• Why did we start using .xql? I originally used Punch code to model conventions, let's keep using .xql (this has gone on too long)
