theme_foundation: Foundation Theme
In elo2zero/juicystat.vis: Html widgets for juicystat

This theme is designed to be a foundation from which to build new themes, and not meant to be used directly. theme_foundation is a complete theme with only minimal number of elements defined. It is easier to create new themes by extending this one rather than theme_gray or theme_bw, because those themes those themes define elements deep in the hierarchy.

`base_size`	base font size
`base_family`	base font family

This theme takes theme_gray and sets all colour and fill values to NULL, except for the top-level elements (line, rect, and title), which have colour = "black", and fill = "white". This leaves the spacing and-non colour defaults of the default ggplot2 themes in place.
