[RD] high / low lines pv4 v1

==================================================================
July 7 2019 - high / low lines pv4 v1 - by RootDuk
==================================================================

Easy script to draw some lines on the input variable barsback.
You can extend the lines on the sides: left, right, both or none.

With the show variables (bools) you can show or hide the lines
Lines: high to high, low to low, high to low or low to high

Easy way to find support / resistance based on the past with
extended lines. Cheers and enjoy

Notes
===================================================================
Hope TV (pinescript) will get color inputs for line or a type color so we can
easily create inputs for colors for lines. Now its static. If someone knows
another way, pls let me know, i'll integrate it
