Convert IRangesOverview.Rnw to IRangesOverview.Rmd

@jwokaty please review this PR I have reviewed it once using the checklist and make sure that R CMD build contains html. After your review we will ask @hpages for final review.

Note: The plots position is quite different in the html document but I believe that in the pdf plots are appeared at the middle of the code blocks which is not possible to generate in html the current position of plots look good to me.

Attached PDF HTML for your reference.

We will be using this checklist to review my PR I have reviewed it myself, Please review my changes and let me know if any more changes are required any suggestion will be appreciated.

Note: During the review I noticed that pdf has

> if (!require("BiocManager"))
+ install.packages("BiocManager")
> BiocManager::install("IRanges")

I Remember that One of the requirements of a vignette is that it must not install anything without the user's knowledge. But the code label uses eval=FALSE to stop running that code chunk so I think there is no problem.
