Adding new visualization functions to:

• Visualize Run Differentials within a season
• Visualize Standings timeline (Game Behind & Winning Percentage) within a date period in a season

Hi @BillPetti,

I’m wondering if this function would be included in the next release.

Thanks for your thoughts.

@darh78 Can you please submit pull requests to the development branch? This way I can test the functions more easily and ensure they work without affecting the master branch. Also, I only see .R files here. You should run devtools::document to generate the .man files as well as automatically generate any import or export updates to the NAMESPACE file.
