=head2 context

The name of the -context- which determines at what point the value 
can be computed and collected, and into which Context -object- it
will be cached (although, since Context objects overlay in a hierarchy,
lower-level contexts can automatically access the datapoint values of the 
higher-level contexts (i.e. 'set' datapoints are implied in 'change'
context but not 'column' datapoints. This is just standard belongs_to vs
has_many logic based on the way contexts are interrelated, regardless of
how or if they are actually stored)
