Detailed Description

Contains the ReadDataComponent Behavior/Command.

Causes the indicated measurement to be made by setting the requestData flag on the reader to true. Command is satisfied if data is returned by the reader's writers.

Todo:: add timing options, etc. to meet requirements: Allow science data acquisition to occur asynchronous to core vehicle control and Allow science data acquisition to occur at a variable loop period

ReadDataComponent.h should only be included by ReadDataComponent.cpp Other classes should include ReadDataIF.h
