Simulated Annealing now supports configurable options to tune it
Strategies are now implemented as protocols, options for a strategy is set on the strategy struct, which is then called by strat to solve the problem. The only user facing change to this is set_strategy/2
```
# was
set_strategy problem, My.Strategy
# now
set_strategy problem, %My.Strategy{}
```
Aruspex no longer delegates it's api to Aruspex.Server, please use Aruspex.Server directly instead.
Changes to Aruspex.Server's API, post/2, variable/2, and set_search_strategy/2 now return the same pid used as the first argument. This change allows for cleaner API usage:
```
pid
|> variable(:x, 1..2)
|> variable(:y, 1..2)
|> post(linear :x + :y == 1)
|> find_solution
```
