TYPES:
d = dict
l = list
s = string
i = int
b = binary (True/False)
o = object

- pkey's dict key is the 40-char key ID of the primary key
- "==>" indicates the next item is a dict and the current item may contain one or more elements of the same format,
	"++>" is a list,
	"-->" is a "flat" item (string, object, int, etc.)
-"status" is one of "an UPGRADE", "a DOWNGRADE", or "a NEW TRUST".

keys(d)	==>	(40-char key ID)(s)	==>	pkey(d)		-->	email(s)
								-->	name(s)
								-->	creation (o, datetime)
								-->	key(o, gpg)
					-->	trust(i)
					-->	check(i)
					-->	local(b)
					-->	notify(b)
					==>	subkeys(d)	==>	(40-char key ID)(s)	-->	creation
					-->	change(b)
					-->	sign(b)
					-->	status(s)
					==>	uids(d)		==>	email(s)		-->	name(s)
												-->	comment(s)
												-->	email(s)
												-->	updated(o, datetime)

for email templates, they are looped over for each key dict as "key".
so for example, instead of specifying "keys['748231EBCBD808A14F5E85D28C004C2F93481F6B']['pkey']['name']",
you instead should specify "key['pkey']['name']". To get the name of e.g. the second uid,
you'd use "key['uids'][(uid email)]['name'].

the same structure is available via the "mykey" dictionary. e.g. to get the key ID of *your* key,
you can use "mykey['subkeys'][0][0]".

you also have the following variables/lists/etc. available for templates (via the Jinja2 templating syntax[0]):
- "keyservers", a list of keyservers set.
