Compute forward mode Taylor coefficients for result of op = CsumOp.

This operation is

	z = s + x(1) + ... + x(m) - y(1) - ... - y(n).
Template Parameters:
Basebase type for the operator; i.e., this operation was recorded using AD< Base > and computations by this routine are done using type Base.
Parameters:
plowest order of the Taylor coefficient that we are computing.
qhighest order of the Taylor coefficient that we are computing.
i_zvariable index corresponding to the result for this operation; i.e. the row index in taylor corresponding to z.
argarg[0] is the number of addition variables in this cummulative summation; i.e., m.
arg[1] is the number of subtraction variables in this cummulative summation; i.e., m.
parameter[ arg[2] ] is the parameter value s in this cummunative summation.
arg[2+i] for i = 1 , ... , m is the variable index of x(i).
arg[2+arg[0]+i] for i = 1 , ... , n is the variable index of y(i).
num_paris the number of parameters in parameter.
parameteris the parameter vector for this operation sequence.
nc_taylornumber of colums in the matrix containing all the Taylor coefficients.
taylorInput: taylor [ arg[2+i] * nc_taylor + k ] for i = 1 , ... , m and k = 0 , ... , q is the k-th order Taylor coefficient corresponding to x(i)
Input: taylor [ arg[2+m+i] * nc_taylor + k ] for i = 1 , ... , n and k = 0 , ... , q is the k-th order Taylor coefficient corresponding to y(i)
Input: taylor [ i_z * nc_taylor + k ] for k = 0 , ... , p, is the k-th order Taylor coefficient corresponding to z.
Output: taylor [ i_z * nc_taylor + k ] for k = p , ... , q, is the k-th order Taylor coefficient corresponding to z.
