[NEW FEATURE] Define verbose mode for warnings

[tobias-liaudat]

Is your feature request related to a problem? Please describe.
This is requested to solve this : issue on the MCCD package.

In summary, the MCCD algorithms uses some optimization algorithms form the ModOpt package. For that the gradient class GradParent() is used from .opt.gradient.py and the function check_npndarray() from .base.types.py throws the warning 'Making input data immutable.' for each instance of the gradient class I have when I run the algorithm.

The main issue is that when the MCCD algorithm is run over a big amount of data, it outputs some big stdout files that are unwanted.

Describe the solution you'd like
It could be possible to add a verbose attribute to the GradParent() class that would be passed to check_npndarray() in order to control its behaviour. As the function check_npndarray() has a verbose variable but it is defaulted to True always in that case.
