Return the minimal CFiniteSequence that generates the sequence.
Assume the first value has index 0.
INPUT:
- ``sequence`` -- list of integers
- ``algorithm`` -- string
- 'sage' - the default is to use Sage's matrix kernel function
- 'pari' - use Pari's implementation of LLL
- 'bm' - use Sage's Berlekamp-Massey algorithm
OUTPUT:
- a CFiniteSequence, or 0 if none could be found
With the default kernel method, trailing zeroes are chopped
off before a guessing attempt. This may reduce the data
below the accepted length of six values.

With Berlekamp-Massey, if an odd number of values is given, the last one is dropped.
