make this repo an R package

[raynamharris]

I found some documentation on best practices for GitHub repos and R packages (mainly this one https://github.com/ropensci/rrrpkg and this one https://kbroman.org/pkg_primer/)

So, I decided to make this repo a package. This reuired a few changes:

• rename my scripts directory to analysis (commits b39ef4e and 851efb7)
• adding a DESCRIPTION file (commit dcefb56)
• reneme this repo from dove_parents_RNAseq to DoveParentsRNAseq because titles can't have underscores (commit cb3e6ac)

It works! Other people should be able to use install_github("macmanes-lab/DoveParentsRNAseq") to load the data and function (once it's not private).

still need to

• move functions out of analsis and into a new directory R
• add a man directory with documentatoin
• add a NAMESPACE file
• make repo public

moved printplotcontrasts function and added documentation in commit 7e56177

Note: it's nice to use cache=TRUE when experimenting with the data anlysis pipeline, but these cache files must be deleted before packing the repo

added namespace with commit 40a5015

and here's the one-liner to make a SummarizedExperiment for easy loading of data
