12th April 2018	SG	SACAMOS: Initial release

18th-22nd June  CJS Create V4 branch for additional developments as follows:
                    1. Iterative solver in Finite Element solution of 
                       laplace equation based on the biconjugae gradient 
                       method
                    2. Implementation of a new ground plane model in which 
                       the groound plane is the x axis and the outer boundary
                       condition on an open problem is applied on a semi-circular 
                       region centred on the origin
                    3. Implementation of a new flex cable model which allows for 
                       multiple layers of conductors within the dielectric
25th June   CJS    Add the nex flex cable test cases  EDGE_COUPLED_STRIPLINE and
                   SYMMETRIC_STRIPLINE to test the new flex cable model

13th July CJS      fix error in creaating circuit symbols: incident field nodes were missing...

22/10/2019 CJS.    Fix numbering error for overshields following a reported error. 
                   Successfully re-run all the automatic test cases and upload the update
                   to the repository.

23/10/2023 CJS...  Start to allow the frequency dependent inductance calculation using FastHenry2.

                   Initially for bundles.

                   
30/10/2023 CJS.    Correct equation 3.21 in Theory manual
