[encrypted-media] "tracked" sessions: "record of key usage" is undefined

ddorwin has just created a new issue for 
https://github.com/w3c/encrypted-media:

== "tracked" sessions: "record of key usage" is undefined ==
_record of key usage_, which was added by pull request #54, is used as
 a variable in several algorithms but not clearly defined anywhere. It
 should probably be "this object's _record of key usage_" and be 
initialized in `createSession()`.

In addition, it would probably be helpful to provide information about
 the variable. For example, that the record contains entries, as 
referenced in section 7.5.2 [Encrypted Block 
Encountered](https://w3c.github.io/encrypted-media/#encrypted-block-encountered).
 It might also help to make it plural somehow, since it has records 
for all keys in the session. (Both of these will be moot if the change
 proposed by #80 is made.)

_first decrypt time_ and _latest decrypt time_ are also undefined in 
section 7.5.2
