     * Returns true if the parent (this) package  can be built in the same escrow 

     * build iteration as the dependent package. 

     *  

     * This is a complex decision and has a few built in assumptions. 

     *  

     * If the dependent package is 'generic' then the parent package can be built 

     *  

     * If the parent package is generic then is can only be built if the dependent is 

     * also generic. Otherwise we must assume that the parent package is an agregator 

     * package and requires artifacts from the dependent package built by all of its 

     * required build machines. 

     *  

     * If both packages are not generic, then if the build standards of the parent and the 

     * dependent are identical then 

     *  

     *      If we have one build standard, we can build the parent in this iteration as

     *      the dependent package has been completely built.

     *  

     *      If we have more than one build standard ( but they are identical ) then we

     *      ASSUME that we can build the parent in this iteration. The assumption is that

     *      there is no mixing between build machines. ie: Windows consumer users Windows

     *      artifacts and the Linux consumer uses Linux artifacts ...

     *  

     * If both packages are not generic and the build standards are not identical, then 

     * things get hard. The safest solution is to assume the parent cannot be built in this 

     * iteration. This is not a bad assumption.
