LGTM

Row 77, y, t, x = lsim(sys, u[, t]; x0, method]) in the lsim docstring, has an extra ] (or maybe missing a [).
Not related to this PR, just saw it and thought I would note it in case you felt like fixing.

Also unrelated to the PR, is there a way to nicely reference lines that are "out of scope" of the current PR? I don't get the same button as I do on the lines that are close enough to the changes. Maybe reasonable most of the time, but very annoying when you want to note something that are like 1 line too far away.

Yeah it's quite annoying, I'm not aware of any way other than a standard source-code link :/

* Yet another fix for  struct_ctrb_states. Closes #475 (#541)

* bugfix for negative real pole in damp (#539)

* Fix #546

* minor typographic changes

* optional epsilon in dcgain (#548)

* optional epsilon in dcgain

* Update analysis.jl

* bugfix: use correct type for saving dde solutions (#549)

Would be good to have a regression test for `BigFloat` data which was the reason I found this bug. That seems slightly involved to fix though.

I assume that this would also have failed for `ComplexF64`, so eventually a test for that too would be good.

* bugfix dcgain (#551)

* correct type of initial state in step (#553)

* remove version checks

* Fix spacing in type printing

* write `struct_ctrb_states` in terms of `iszero` instead of `== 0` (#557)

* write `struct_ctrb_states` in terms of `iszero` instead of `== 0`

The reason is that `iszero` always returns a bool, whereas `== 0` may return anything. The difference appears for symbolic variables where
```julia
julia> q0 == 0
q0(t) == 0

julia> iszero(q0)
false
```

* Update simplification.jl

* remove `issmooth` (#561)

* remove issmooth

* drop extra `]`

* Return a result structure from lsim (#529)

* Return a result structure from lsim

This is by design a non-breaking change to the lsim interface since the structure allows both getindex and destructuring to behave just like if lsim returned a tuple of arrays like before.  Indeed, the tests for lsim were not touched in this commit.

This commit also adds a plot recipe to the result structure. All plot recipes for lsimplot, stepplot, impulseplot have been replaced by the new recipe. This is a breaking change since the names of the previous plots no longer exist. A slight change is that the plots for a step response no longer show the text "step response", but I think that's an acceptable change, the user can supply any title they prefer themselves.

* remove automatic title

* introduce additional abstract result type

* do not destructure sys

* remove LQG (#564)

The functionality was very buggy and poorly tested. A much improved version with proper tests are available in https://github.com/JuliaControl/RobustAndOptimalControl.jl/blob/master/src/lqg.jl

* pole->poles tzero->tzeros (#562)

* update usage of plot for step simulation

* add doctest filters

* add release notes

* Update README.md

* Update README.md
