Changeset 7469 for trunk/psModules/src/camera/pmFPARead.c

Message:

Was having trouble reading and writing concepts at different levels. Added 'propagateUp' and 'propagateDown' flags to the pmConceptsRead and pmConceptsWrite functions so we can read up and down the hierarchy. For example, when you read a header at the chip level, it may be a PHU so that you want the FPA to also read concepts from it if it doesn't have its own HDU, and you want the cell to read concepts from it if it doesn't have its own HDU. But if I add a PHU, I only want to propagate upwards, because the downwards propagation will occur when I read the header lower down.
