Add annotations to 'location of' and 'located in'

RO_0001025 located in
- add textual definition: a relation between two independent continuants, the 
target and the location, in which the target is entirely within the location
- add example of usage: my brain is located in my head
- add example of usage: this rat is located in this cage
RO_0001015 location of
- add textual definition: a relation between two independent continuants, the 
location and the target, in which the target is entirely within the location
- add example of usage: my head is the location of my brain
- add example of usage: this cage is the location of this rat

The editor note on "located in" is correct but difficult to understand. Should 
I try to simplify it, or let it stand?

"Location as a relation between instances: The primitive instance-level 
relation c located_in r at t reflects the fact that each continuant is at any 
given time associated with exactly one spatial region, namely its exact 
location. Following we can use this relation to define a further instance-level 
location relation - not between a continuant and the region which it exactly 
occupies, but rather between one continuant and another. c is located in c1, in 
this sense, whenever the spatial region occupied by c is part_of the spatial 
region occupied by c1.    Note that this relation comprehends both the relation 
of exact location between one continuant and another which obtains when r and 
r1 are identical (for example, when a portion of fluid exactly fills a cavity), 
as well as those sorts of inexact location relations which obtain, for example, 
between brain and head or between ovum and uterus"

Since location has many of the same temporal problems as continuant parthood 
(see issue 43), I'd like to add editor notes pointing to a longer discussion in 
the wiki.

both terms:
- add editor note: Most location relations will only hold at certain times, but 
this is difficult to specify in OWL. See
