Improve description of Shiny app

[ahudde]

Two comments from @bahung:

• Structure: Please add one section to describe the components of greeks, each with visualizations accordingly, especially when one of your paper main contributions is "Also, it is the only R package with included interactive visualization"
• What is "Shiny app"? If it is a way to display the interactive visualizations, I think it is better to explain the mechanism to produce such visualizations and how easy to interact with them.

Dear @bahung, Please have a look at the updated the to include a description of the shiny app. Furthermore, I updated the reference manual greeks.pdf, which you can find on this repository, or on cran: https://cran.r-project.org/web/packages/greeks/greeks.pdf. What do you think of the description of the function Greeks_UI()? Is this enough?

Yours, Anselm

Hi @ahudde,

I saw the updates regarding the UI as follows: "For performance reasons, just the Black-Scholes model is possible, and for some cases, the set of Greeks is limited. On the y-Axis, the option value resp. the value of the greeks are displayed, for the x-axis, several parameters like initial_price or time_to_maturity are possible."

It would be nice if you can be more specific:

1. Why only BS is available?
2. For "and for some cases, the set of Greeks is limited" --> Does the set depend on the options types? If so, please mention that.

After you finish, I think you can close this issues.

Thank you for your updates, BaHung
