Add an example of LCD text display in indicateText doc and README (or is it in the normal gallery but not easily discoverable?)

[patricksurry]

should also include more example code fragments throughout the doc. some way to test documentation examples?

[patricksurry]

describe the coding patterns used to build g3 gauges, similar to d3: ie. you are typically calling a factory method that return a configurable renderer function. you call various methods to configure that renderer, and finally apply it by calling the renderer with a target element.

[patricksurry]

include all the examples from the npm run start gallery. maybe insert static snippets in the doc via d3-node if inline styles work?
