Backend decorator

the backend decorator tells the platform what you want to do with the values stored inside the variables used by your custom action \[bedecorator(ioproperty = direction output)] the ioproperty property allows you to choose one of four possible directions, that will give you more control on over your custom action none = 0, input = 1, inputoutput = 2, output = 3, the most useful are input and output while using input the custom action expects to receive the value from the user and with output it will return a value that could be one or more inputs that were used internally the none option is the default if the ioproperty is not mentioned the inputoutput option is used when a property needs to be both input and output, because it must first receive a value before it uses it in the backend
