* `make_IPM()` is more flexible for climate input to simplify scripts. 
Single rows matrix and data.frame are now accepted. 
This replace `climate <- drop(as.matrix(subset(climate_species, ...)`.

* `species()` class constructor has now default values and should be preferred to `new_species()`.

* Added a `NEWS.md` file to track changes to the package.

* Changed package name to `{matreex}`.

* Add disturbance model from Julien.

* Class `ipm` was modified and *invalidate* previous script output (if saved as
.Rds/.Rdata).

* Idea from Arnaud to precompute mu values to speed up in-simulation integration

and modify climate. This kind of simulations takes longer but is very flexible. 
New class `mu_gr`.

* Refactorisation of harvest process for Uneven and Even process. 
Uneven works with multi species.

* Refactorisation of integration process to gain time and allow a more general
function (added input choices).

* Multi species simulations works with 1 to n species in a general setup. 
Also created a generic output format usable in `{tidyverse}`.

* Add functions to load old IPMs and modify them in new class (`ipm`, `species`
, `forest`).

* Packaging functions from [Kunstler *et al* (2020)](https://doi.org/10.1111/1365-2745.13533) under initial name `{treeforce}`.
