Documentation - avoid excessive use of "please"

The word "please" is used in ~ 50 places across OCCT documentation, and in most of these places it looks excessive. "Please" is good in direct messages to particular persons (e.g. in e-mail) when you ask for something, but not in technical documents intended for wide audience when you just provide information.

See for instance Google style guide:

Even more, when "please" is still useful, use of comma after it should be avoided except when it is really necessary. Note that normally comma is not needed after "please" in English, and when it is present, it emphasizes this as strong request. We unlikely need to have such requests in our docs. More detailed explanations can be found elsewhere, e.g.:
