! NAME

!
! AUTHORS
!     Chris Smartt
!
! DESCRIPTION
!     The cable_bundle_model_builder brings together a number of cable models, ground plane and 
!     overshield models with their position in the bundle cross section as required to build a model of a cable bundle. 
!     The output of the bundle_model_builder code is a file name.bundle which can be used to generate Spice cable bundle models
!     for a particular modellling scenario using the program spice_cable_bundle_model_builder
!
!     The input to the program is the name of a cablebundle specification file. A file name.bundle_spec must exist, containing
!     all the data required to specify a cable bundle.
!
!     The .cable files referred to in the .bundle_spec file are looked for in a directory specified in the .bundle_spec file. 
!     This may be the local directory (./) or another specified path. In this way the software can interact with a 
!     library of cable models (MOD).
!
!     The output of the cable_bundle_model_builder code is a file name.bundle which can be used as an input to the 
!     spice_cable_bundle_model_builder software
!
!     The .bundle file is placed in a directory specified in the .bundle_spec file. This may be the local directory (./) 
!     or another specified path. In this way the software can interact with a library of cable models (MOD).
!
!     The program may be run with the cable bundle name specified in the command line i.e. 'cable_bundle_model_builder name'
!     or it the name is absent from the command line, the user is prompted for the name.

! HISTORY
!
!     started 17/11/2015 CJS: STAGE_1 developments
!     started 3/2/2016 CJS:   STAGE_2 developments - multi-conductor bundles
!     started 22/3/2016 CJS:  STAGE_3 developments - multi-domain bundles (shielded cables)
!     started 13/4/2016 CJS:  Simplify the code and improve the notation. At this stage the format of the .bundle_spec file changed
!                             Shift the complex bundle building processes into BUNDLE_DOMAIN_CREATION/create_global_domain_structure.F90
!     20/4/2016 CJS: Allow the code to read x,y  OR x, y, theta formats for cable position and orientation. Similar for ground plane
!     27/4/2016 CJS: Include a conductor based impedance (loss) model
!     29/6/2016 CJS: Check that the cables are all on one side of the ground plane if it is present
!     December 2016 CJS Version 2: Rationalise cable types so that there is only a single version of each type of cable
!     24/2/2017 CJS Allow the input name to include a path i.e. the _spec file does not need to be local.
