+Limit evaluators allow a telemetry integrator to define which limits exist for a 
+telemetry endpoint and how limits should be applied to telemetry from a given domain object.
+
+A limit evaluator can implement the `evalute` method which is used to define how limits
+should be applied to telemetry and the `getLimits` method which is used to specify 
+what the limit values are for different limit levels.
+
+Limit levels can be mapped to one of 5 colors for visualization: 
+`purple`, `red`, `orange`, `yellow` and `cyan`.
+
+For an example of a limit evaluator, take a look at `examples/generator/SinewaveLimitProvider.js`.

 Open MCT (Open Mission Control Technologies) is a next-generation mission control framework for visualization of data on desktop and mobile devices. It is developed at NASA's Ames Research Center, and is being used by NASA for data analysis of spacecraft missions, as well as planning and operation of experimental rover systems. As a generalizable and open source framework, Open MCT could be used as the basis for building applications for planning, operation, and analysis of any systems producing telemetry data.
