Provides the generic function `size`

and S4 methods to get the size of
each element from objects based on `itemMatrix`

. For

an object of class `transactions`

).

`size`

returns a numeric vector of length `length(x)`

. Each
element is the size of the corresponding element (row in the matrix) in
object `x`

. For rules, `size`

returns the sum of the number of
elements in the LHS and the RHS.
