Minor improvements

@ChrisRackauckas I am just rewriting parts of the documentation as I read along. Mostly rephrasing things I find confusing at first read.

I need your input for the following. Specifying adaptive = false in solve turns off adapting time step over the course of numerical integration, but it still chooses the initial time step on it's own right?

I believe if adaptive=false then you need to supply dt, though I haven't checked that in a long time. dt is the initial time step and if it's not adaptive then it's all time steps.

Got it, I missed that we need to supply dt with adaptive=false here.
