Reduce slide header size

[Matt-Brigida]

We need to figure out how to reduce the header size for select (not all) slides. This will allow us to display larger apps.

Could you give an example of a slide that needs a reduction in header size. Would the {.smaller} attribute to the header be sufficient? http://rmarkdown.rstudio.com/ioslides_presentation_format.html

For example, in this slide I could add a dividend yield slider if we could shift the app higher on the slide. Now, adding the slider will run it into the logo.

{.smaller} doesn't seem to work, but it is going to be some bit of css.

check the commit I just pushed -- it uses the div() function and allows you to set your own slider size, only problem however is that you need to take the ticks off from underneath the slider to keep it looking clean. I think the only other way to resolve this issue would be to write a custom css, which I don't know how to do, but could certainly learn.

This looks great. I'll add the dividend to the calculation. I'd still like to get rid of that header -- but this is not urgent.
