• What is the current behavior? Indexing error in line 505 and 510 of "bms/core.py" (VariablesValues method)

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem Avoid reference to other packages

  
  import bms
  from bms.signals.functions import Step
  from bms.blocks.continuous import Gain

te = 10 ns = 500

R = Step(('In', 'R')) Y = bms.Variable(('Out', 'Y'))

G = Gain(R, Y, 1)

system = bms.DynamicSystem(te, ns, [G]) simulation = system.Simulate() system.VariablesValues(Y, t=1)

* **What is the expected behavior?**
>>> 1 (Print a number)

* **What is the motivation / use case for changing the behavior?**
The function dont work

* **Possible fixes**
cast "i" variable in line 505 and 510 like "int(i)"

`variables.values[int(i)]*((ti-t)/self.ts+1)+variables.values[i+1]*(t-ti)/self.ts)`

* **Please tell us about your environment:**
