Theorem vciOLD

Description: Obsolete version of cvsi . The properties of a complex vector space, which is an Abelian group (i.e. the vectors, with the operation of vector addition) accompanied by a scalar multiplication operation on the field of complex numbers. The variable W was chosen because _V is already used for the universal class. (Contributed by NM, 3-Nov-2006) (New usage is discouraged.) (Proof modification is discouraged.)
