## Observation

In this section, I introduce the commands to access the observation. `CLIC` knows only one observation at a time, the current observation. The other observations already read are kept in memory so subsequent calls do not have to read again the corresponding records. The limit to that scheme is the amount of memory. In case, not enough memory is available to get an new observation, `CLIC` will remove the oldest observations in the cache until sufficient room is found.
