Force increasing Range

[alexandremcosta]

Keep the same behaviour as with earlier elixir versions.

Fix:

 warning: Range.new/2 and first..last default to a step of -1 when last < first. Use Range.new(first, last, -1) or first..last//-1, or pass 1 if that was your intention

Issue #271

Be aware I wasn't able to run tests locally. I have MongoDB running locally, but the test suite doesn't connect to it, and I can't find instructions on how to do that.

I'm not sure if the solution solves the warning here, because you use a positive step value of 1. The warning is only printed if the step gets negative:

iex 1> Range.new(1,10)
1..10
iex 2> Range.new(10,1)
warning: Range.new/2 and first..last default to a step of -1 when last < first. Use Range.new(first, last, -1) or first..last//-1, or pass 1 if that was your intention

I assume the step value can be positive and negative.

Thank you. I will change your code a bit to support different step values.
