Model with named tables having minimum, maximum, and step

[pedro-andrade-inpe]

Implement the possibility of having minimum, maximum, and step attributes in a named table to define a set of possible values for a given attribute of a Model, such as:

MyModel = Model{
    par1 = {
        minimum = 3,
        maximum = 8,
        step = 0.5
    }
}

m2 = MyModel{par1 = 5}
