1.2.1 Return the shape parameters the component
The getshape function returns the shape parameters of a component in a record. As different shapes can have a differing number and type of parameters the shape parameters are returned in a record with fields that correspond to parameters relevant to the current shape.
For a point shape there are only two fields; type and direction. These are the shape type, and the reference direction. These values are also returned by the shapetype and getrefdir functions.
For both the Gaussian and disk shapes there are three additional fields; majoraxis, minoraxis & positionangle. These are angular quantities, and hence are records with a value and a unit.
An index specifying which component. An integer between 0 and one less than the list length, inclusively
