*May 24, 2016: We're still staging MDFTextAccessibility, feel free to poke
around, but non-code things like CocoaPods support and continuous integration
testing will be ramping up over the next few weeks. The API is relatively stable
at this point.*

## Accessibility of text

Apps created for the widest range of users should ensure that users can read
text presented over any background. While the legibility of text depends on many
things, a great start is to provide a sufficiently large *contrast ratio*
between foreground text colors and their background colors. The contrast ratio
of two colors is a measurement of how much the brightness of two colors differ.
For example, white on dark grey might have a contrast ratio of 9:1, while white
on medium grey might only have a contrast ratio of 4:1. In general, larger
contrast ratios are better and will ensure the widest range of users can easily<commit_msg>Fixed stray `+` in README.md.<commit_after>MDFTextAccessibility assists in selecting text colors that will meet the
