Matrix of factors : `maple_ifactors`

`maple_ifactors` has an integer *n* (or a list of integers)
as parameter.

`maple_ifactors` decomposes the integer (or the integers of the list) into
prime factors, but the output follows the Maple syntax :

it is a list with +1 or -1 (for the sign) and a matrix with 2 columns and
where the lines are the prime factors and their multiplicity (or a list of
lists...).

Input :
`maple_ifactors(90) `

Output :
`[1,[[2,1],[3,2],[5,1]]]`

Input :
`maple_ifactor([36,52]) `

Output :
`[[1,[[2,2],[3,2]]],[1,[[2,2],[13,1]]]]`
