Complete table of exported Units in documentation

julia> u"u"
u

Where do I go to find out what u is? I think it is Daltons (from checking Wikipedia) but there does not seem to be anywhere in the documentation to verify this. A complete table to ctrl+f would be incredibly helpful, just for sanity checking.

Yes: https://github.com/PainterQubits/Unitful.jl/blob/cc3adef8e4cd72f6f8951cca29f9a8d19a24e5cb/src/pkgdefaults.jl#L162

Having an automatically-generated list of these units in the documentation is a good idea.

#476 should allow for something like this using Julia's help system; could that be at all useful for this?
