Add documentation

help?> gaussjacobi
search: gaussjacobi

  No documentation found.

  FastGaussQuadrature.gaussjacobi is a Function.

  # 2 methods for generic function "gaussjacobi":
  [1] gaussjacobi(n::Integer, a::Float64, b::Float64) in FastGaussQuadrature at /Users/solver/.julia/packages/FastGaussQuadrature/G3Izs/src/gaussjacobi.jl:7
  [2] gaussjacobi(n::Number, a::Number, b::Number) in FastGaussQuadrature at /Users/solver/.julia/packages/FastGaussQuadrature/G3Izs/src/gaussjacobi.jl:1

Can I make a document with Documenter.jl?

[dlfivefifty]

To add help documentation you just add a string before the function definition: if in a file I write

# foo.jl
"""
foo(x) does nothing
"""
foo(x) = nothing

Then I get:

help?> foo
search: foo floor pointer_from_objref OverflowError RoundFromZero unsafe_copyto!

  foo(x) does nothing

Ah, thanks, I know that.

I was planning to add jldoctest for clarity. To check the tests, we need Documenter.jl. I thought this is a goot oppotunity to add more documents, but my concern was that adding Documenter.jl could be bigger change.

I strongly support adding Documenter.jl so will happily help

[hyrodium]

Okay, I'll make a pull request!

The github pages works fine, so I'll close this issue.
