Consider a simple code to solve an ODE by `DifferentialEquations.jl`

shown in the documentation:

```
using DifferentialEquations
f(u,p,t) = 1.01*u
u0 = 1/2
tspan = (0.0,1.0)
prob = ODEProblem(f,u0,tspan)
sol = solve(prob)
```

In the last line, `solve`

seems to pick an appropriate algorithm for the given problem and use it. Is there a way to show which algorithm is picked by `solve`

?

We can choose a specific algorithm at will by changing the line to something like

```
sol = solve(prob, Tsit5())
```

where `Tsit5()`

indicates the algorithm to use. But I would like to know which algorithm was picked by `solve`

when the algorithm was not specified by the user, because for my problem the default algorithm picked by `solve`

seems to perform pretty well.
