Parser_v1.1

Addition

• In the context of augmenting the direct current analysis, the implementation of the Ptran algorithm, along with the visualization of results, is presented.
• When initialized with an initial value of zero for three test circuits, it consistently yields accurate solutions.

Parser_v1.0

• Support identification and data storage of components such as resistors, capacitors, voltage sources, current sources, and BJT devices.
• Support solving using the third-party library Eigen.
