Output formats

This release adds support for all ggsave-supported output formats, including png, pdf, etc.

The one with shapes and sizes

Support has been added for customizing the shape and size of the dots in the central ggplot, along with bug fixes, quieting down the warnings, and a much improved readme file that actually shows most of the options.

Fonts and support for appending plots

Reasonable support for additional fonts is now working. R's standard "sans" and "serif" fonts should work out of the box, and any font can be passed into the function, but might require adjustment with "nudge_y" and "nudge_width" to line up perfectly. Additionally, support for adding a ggplot object to the right side of the figure has been added and is in the experimental stage.

Development version 0.2.0

Beta version, but generally working. Some irregularities in vertical spacing are still present.
