 - This refactor significantly reduces loops and should reduce time to build ITD JuMP models.
 - This refactor also allows building ITD models where multiple distro. systems can be connected to same trans. system bus and KCL constraints are not duplicated.
 - Bumped PMITD compatibility of `PMD` to the latest version (i.e., v0.15.2).
+- Updated `README.md` with minor revisions.

-`PowerModelsITD.jl` is an extention package of PowerModels.jl and PowerModelsDistribution.jl for Steady-State Integrated Transmission-Distribution (ITD) Power Network Optimization. It is designed to enable computational evaluation of emerging power network formulations and algorithms in a common platform. The code is engineered to decouple problem specifications (e.g. Power Flow, Optimal Power Flow, ...) from power network formulations (e.g. AC polar, AC rectangular, linear-approximation, SOC-relaxation, ...) on both transmission and distribution system(s). Thus, enabling the definition of a wide variety of ITD power network formulations and their comparison on common problem specifications.
