Hi! I'm new to Julia and I hope to use it for an agent-based model that I'm building.
I've downloaded and installed the DataStructures<https://github.com/JuliaLang/DataStructures.jl>package, and am trying to use the mutable_binary_minheap structure. I can instantiate a minheap, push to it and pop from it, but two very important functions claim that they're not defined: update! and top. Both return an "ERROR: x not defined". But when i look at the source code<https://github.com/JuliaLang/DataStructures.jl/blob/master/src/heaps/mutable_binary_heap.jl>they both seem correctly defined (the code on my machine matches that online). This error is there with 0.21 as well as 0.3 pre-release.
