Expandable

Expandable are all objects that can be expanded, like: 5(2 + 3x) or -7x(4x - 1) or (2x - 3)(8x + 2) or -(7x - 6)
So they are always a Product of two Exponenteds. One of these Exponenteds at least is a Sum of at least two terms. It might well be that the exponent is assumed to always be Value(1). Maybe make it clear someday...

The binomial like (3x + 2)² are Expandables treated in the BinomialIdentity class

Possible args for __init__() :
(Exponented, Exponented) | (RANDOMLY, <type>)
The usable types when creating a randomly Expandable:</type>

• monom0_polyn1 will create this kind of objects: 5(3x-2)
• monom1_polyn1 will create this kind of objects: -5x(2-3x)
• polyn1_polyn1 will create this kind of objects: (5x+1)(3x-2)
• minus_polyn1_polyn1 will create: - polyn1_polyn1
• sign_exp will create ±(±ax²±bx±c) | ±(±bx±c) | ±(±ax²±c) | ±(±ax²±bx)

Options: reversed | randomly_reversed=nb

• reversed will change the sums' order. This is useless if the sums are the same kind of objects (like (2x+3)(3x-7))
• randomly_reversed=0.3 will change the sums' order in a ratio of 0.3
