initial implementation of typewriter architecture; lots to do
reorganize into "app" concept
call it genwriter
and give it a consistent package name
unused func
Validate must also indicate whether a TypeWriter will write for a given type, to avoid empty files
correct logic for whether type will write
stub out container typewriter
implement Write for containers typewriter
ensure that Validate() has been called for a type
move typewriter to its own repo
inflect to its own repo
select standard methods applicable to Type
bring over tests for gen'd code; more to do

Prefer to do this is a more unit-test kind of way, less writing perhaps
limit responsibilities of determineMethods to tags, no type eval; use new ApplicableTo method
rename to evaluateTags
move stuff into methods file
return error later with unknowns, continue collection of known
add methods tests
