zeligDepUpdate: Download Zelig Dependencies Packages

Description

Compares the packages in Zelig-matrix of dependencies to the locally installed packages. Finds local packages that have lower versions than in the corresponding row of the Zelig-matrix. Also, finds packages that Zelig required but are not installed locally. Downloads packages that are locally installed with lower versions and those from the Zelig-matrix that are not installed. The download repository is taken from either the default repos argument or from the URL column of the Zelig-matrix of dependencies.
