Removed magic number for first station id and added it as a constant variable
Removed unused between method since the between method used is part of the Ruby Comparable module
Refactored all between checks and if statement into a private method to check the station id range and throw exception if needed
Removed between old tests since those were not using the correct between method
Added tests for the exceptions when a station ID is out of bounds
