Program execution:

The way in which observing instructions are provided through a `Observing Block' form has been slightly modified and now requires the use of the target pointing scripts through which target coordinates and finding charts can be uploaded directly for execution. Also, it is now possible to define more sophisticated system scripts as part of the observing sequences in an Observing Block, instead of being limited to the use of the script generator which only allows for the definition of (a set of) exposures.
