Add input to previous value of output, if rising edge of trigger port

This block has one Integer input "u", one Boolean input "trigger", an optional Boolean input "reset", an optional Integer input "set", and an Integer output "y". The optional inputs can be activated with the "use_reset" and "use_set" flags, respectively.

The input "u" is added to the previous value of the output "y" if the "trigger" port has a rising edge. At the start of the simulation "y = y_start".

If the "reset" port is enabled, then the output "y" is reset to "set" or to "y_start" (if the "set" port is not enabled), whenever the "reset" port has a rising edge.

The usage is demonstrated, e.g., in example Modelica.Blocks.Examples.IntegerNetwork1.

use_reset	Value: false Type: Boolean Description: = true, if reset port enabled
use_set	Value: false Type: Boolean Description: = true, if set port enabled and used as default value when reset
y_start	Value: 0 Type: Integer Description: Initial and reset value of y if set port is not used
