Summer 2021 Release v1.3

Version 1.3 - 20 Jul 2021

Summary

Reduced coupling among different sections of the codebase by increasing the use of library style modules for all the sub-parts of the c3-toolset. Clean-ups also involved renaming the Optimizers to more intuitive names. Several performance improvements were introduced by vectorized and batched operations.
