Add a control language function cvector, to create a complex vector.
Let vec1 = cvector(50)
will generate a complex vector, with the real part values
increasing from 0 to 49, the imaginary values are set to 0.
Useful in ac loops to store result data.

The modulo function a % n should accept a==0.
The fix adds this to the control section function parser. The numparam
parser already has this feature. n==0 is rejected as usual.
