The genofile cells contain a file name (string). When the file gets read we will capture the state in a file and carry the file name of the new file forward. -In this setup cells simply represent file names (for state). This allows us to simply read and write files in the C code. +In this setup cells simply represent file names (for state). +This allows us to simply read and write files in the C code. Later, when we wire up new propagators we may carry state in memory. The whole point of using this approach is that we really don't have to care! + +Our first simple implementation of the cell will simply contain a string referring to a file. +Cells can be work in progress and incrementally improved. + +## Create propagators + +A propagator contains a list of inputs and an output cell. So we wire up the graph by adding inputs to propagators. +Every propagator has state (too).

On change computation has to happen updating the output cell. |
