Adding an option to make block diagrams instead of circuits

[mjmarques97]

When dealing with electronics, engineers may have to design the control systems for such circuits.
Why not add an option to draw block diagrams, instead of circuits? These diagrams only have rectangles, arrows, and circles.

I've tried adding a tag to this issue but I couldn't

Eventually the program will support generic-block components for drawing systems at a top level. The main goal of the project is to draw circuits in LaTeX.

CircuiTikz is built on top of the tikz LaTeX package which is designed to create vector graphics in latex, flow charts generally use tikz rather than CircuiTikz (since CircuiTikz is a specialized version of tikz). Also there are already tools for Tikz (https://tikzit.github.io/#source) which are well supported.
