Title: Add documentation

The documentation was pulled straight out of Vincent's repository with no reorganization. This organization can be used directly by the following help package:

https://github.com/tshort/HelpTestbed.jl

The documentation can be browsed on github, but it's not the best organization for that. The .rst files are rather buried.

There is a _JL_INDEX_ files that maps help keywords to file location and a one-line description. This is searched by `apropos` and used by `@help`.

Here is a quick example using the help package above:

```jul
julia> apropos("RDatasets", "iris")
RDatasets	iris	Edgar Anderson's Iris Data
RDatasets	Bowley	Bowley's data on values of British and Irish trade, 1855-1899

julia> @help iris
iris not defined

julia> @help RDatasets iris
m.captures	= ["iris", "datasets/iris", "Edgar Anderson's Iris Data"]
Package `RDatasets`, iris

Edgar Anderson's Iris Data
