Updated Syntax

This release updates Shiro to the new Syntax.

Examples of the new syntax can be found in the example_code folder.

The changes can be summarized as:

• Adds port type to port declaration (input, eval, output)

node Point begin
    input x Value
    input y Value
    eval update Point(x[0], y[0])
    output point Value(update[0])
end

• Introduces new option keyword for creating subjunctive nodes. Ports and nodes can now be made subjuncts.

node EndPoints[P1] begin
    option Point -> P1 begin
        x(400)
        y(400)
    end

    option Point -> P2 begin
        x(100)
        y(400)
    end
end

• this can be used to refer to a port
