Initializing help system before first use

# Extended problem description

The investor is unwilling to have small share holdings. We shall explore the following two possibilities to formulate this constraint:

1. Limiting the number of different shares taken into the portfolio.
2. If a share is bought, at least a certain minimum amount MINVAL = 10% of the budget is spent on the share.

We will deal with these two constraints in two separate models.
