Detailed Description

This is the algorithm made to initialize walkers.

It is based on figuring out how many electrons should be on each atom followed by putting them in a gaussian around the atom. This is by far a method which needs a serious overhaul. This was a quick fix to initializing the walkers and the ideas are borrowed from CASINO. This method of initializing is probably very inefficient. This goes without mentioning how ugly the code is. This is a great place for further future work. A huge dent will likely be made on the "Initialization Catastrophe" problem here.
