|  |  D.4.6.10 lsum Procedure from libraryellipticcovers.lib(see  ellipticcovers_lib).
 
Example:Usage:
lsum(L); L list
 
Assume:
L is a list of things with the binary operator + defined.
 
Return:
The sum of the elements of L.
Theory:
Sums the elements of a list.
Eventually this will be deleted and become a more efficient kernel function.
