Memoize is a library which caches a function calls parameters and the resulting value to retrieve them from the cache on succeeding calls with the same function parameters.

This happens opaque to the programmer (just use defmemoize keyword insted of def).

If available in Hex, the package can be installed as:

1. Add memoize to your list of dependencies in mix.exs:

```elixir
def deps do
  [{:memoize, "~> 0.1.0"}]
end
```

2. Ensure memoize is started before your application:

```elixir
def application do
  [applications: [:memoize]]
end
```

Define memoized functions by using the defmemoize macro.

Very simple usage example:

  defmodule TestModule do

    import Memoize

    defmemoize testfun(a, b), do: a + b

  end
  2 = testfun(1, 1) # regular execution of function body
  2 = testfun(1, 1) # result value retrieved from cache, function body not executed
