Meaning of type parameters for Arrays is not discoverable

[dpsanders]

As pointed out by @alanedelman:

While typing AbstractArray indicates that there are two type parameters,
neither ?AbstractArray nor ?Array give information about what those parameters are for.

This also seems to be difficult to discover from http://docs.julialang.org/en/release-0.5/manual/arrays/

  Array{T}(dims)
  Array{T,N}(dims)

  Construct an uninitialized N-dimensional dense array with element type T, where N is determined from the length or number of dims. dims may be a tuple or a series of integer arguments corresponding to the
  lengths in each dimension. If the rank N is supplied explicitly as in Array{T,N}(dims), then it must match the length or number of dims.

Yes, thanks.

A couple of examples in the help text would be nice.
