rename sensor to sensitivity.

sensitivity = find out which observations are affected and over which
portion of the input data the analyzer should be run. this will be moved
next to analyzercontext and execute in analyzer environment.
sensor = server that watches the observatory for changes and tells
supervisor to run analyzers.
