|  |  7.5.5.0. isFsat Procedure from librarydmodapp.lib(see  dmodapp_lib).
 
Example:Usage:
isFsat(I, F); I an ideal, F a poly
Return:
int, 1 if I is F-saturated and 0 otherwise
Purpose:
checks whether the ideal I is F-saturated
Note:
We check indeed that Ker(D--> F--> D/I) is 0, where D is the basering.
