Show example how to access model attributes

[nanophyto]

Something like the pseudo code below would be very useful for analysis (e.g. quickly deriving the size of each P).

N5P5ZD = construct_size_structured_NPZD()

N5PZD.Atributes #to return all parameter values

[radka-j]

Note that attributes can only be accessed from a concrete instance of an object.

In the example above, N5P5ZD = construct_size_structured_NPZD() creates an abstract type that can then be instantiated. Once a concrete model is created (with specific parameter values) one can access its attributes. For example, to get all alpha values:

N5P5ZD = construct_size_structured_NPZD()
model = N5P5ZD()
model.alpha

To get names of all parameters do one of:

fieldnames(N5P5ZD)
fieldnames(typeof(model))
