Major change: Aper Defn; Flux Algor.; Batching

Apertures creation has been modified. After the weighting profile has
been created (for deblending purposes) the aperture is then converted
back to a simple top hat aperture. The weighting function then acts on
the top hat function. This has the impact of equally weighting flux
from all locations inside of the aperture, unlike previous methods
which (sometimes) incorrectly weighted fluxes in the centre of the
aperture.
Related to this change, Parameter file creation has also changed.
Because of the new aperture definition, flux calculation is now a
simple multiplication of the aperture with the image.
Capability for batch running of files has been implemented.
Documentation update coming with full explanation. Essentially,
multiple files/values may be specified for all parameters that are
telescope/image specific (e.g. all maps, directories, catalogue,
magnitude ZPs, etc), and flux measurement will be run over all images
provided.

Documentation update coming soon.
