% CRTBASE.m - Create base vector 
%
% This function creates a vector containing the base of the loci
% in a chromosome.
%
% Syntax: BaseVec = crtbase(Lind, Base)
%
% Input Parameters:
%
%		Lind	- A scalar or vector containing the lengths
%			  of the alleles.  Sum(Lind) is the length of
%			  the corresponding chromosome.
%
%		Base	- A scalar or vector containing the base of
%			  the loci contained in the Alleles.
%
% Output Parameters:
%
%		BaseVec	- A vector whose elements correspond to the base
%			  of the loci of the associated chromosome structure.
