Implement Dynamic Custom X0 creation #199
Description
Mads needs an initial point to run. Usually this point is set as part of the optim pb definition. X0s can also be obtained by LH sampling.
But, for a given problem, custom X0s can be obtained by running an external process.
This process creates and evaluate some points. The best point(s) can be used as a starting point for Mads.
In addition, all evaluated points must be inserted in the cache.
Implement a custom X0 creation callback for this purpose.
