Refactoring SimulatePlanApp

The entry point of our SimulatePlanApp application calls simulatePlan. We need to change it to return the text of any error that could occur.

  "SimulatePlanApp.strMain" should {    "simulate a retirement plan using market returns" in {...}    "return an error when the period exceeds the returns bounds" in {      val actualResult = SimulatePlanApp.strMain(        Array("1952.09,2017.09", "25", "60", "3000", "2000", "10000"))      val expectedResult = "Cannot get the return for month 780.       Accepted range: 0 to 779"      actualResult should === (expectedResult)    }  }

Then, open SimulatePlanApp.scala and change the implementation ...
