Open Source Go Text Annotation Tools

Go package for text annotation. There are two parts to anno, the first is a series of Finder functions that look for interesting articles (which it calls `Notes`) inside the text, returning a slice of Note structs. The second is the Expander, which replaces the text in each Note with something else, like the HTML for a link or something. It tells you the bytes that it found, the `Start` index and a string describing the kind of `Note`. The kind is useful for when you run pass `Finder` objects to the `FindMany` or `FindManyString` functions. Since most of the built-in finders operate on a per field basis (word by word), it made sense to add a special helper called `FieldFunc` that generates`FinderFunc` functions for us, and takes away the repetitive task of breaking the string up, and iterating over each word.
