Provides a n-port network class and associated functions.
Most of the functionality in this module is provided as methods and
properties of the Network Class.
Network Class
| Network([touchstone_file, name]) | A n-port electrical network. | 
 
Connecting Networks
| connect(ntwkA, k, ntwkB, l) | connect two n-port networks together. | 
| innerconnect(ntwkA, k, l) | connect two ports of a single n-port network. | 
| cascade(ntwkA, ntwkB) | cascade two 2-port Networks together | 
| de_embed(ntwkA, ntwkB) | de-embed ntwkA from ntwkB. this calls ntwkA.inv**ntwkB. | 
 
Supporting Functions
| inv(s) | Calculates ‘inverse’ s-parameter matrix, used for de-embeding | 
| connect_s(A, k, B, l) | connect two n-port networks’ s-matricies together. | 
| innerconnect_s(A, k, l) | connect two ports of a single n-port network’s s-matrix. | 
| s2z(s[, z0]) | convert scattering parameters to impedance parameters [#]_ | 
| s2y(s[, z0]) | convert scattering parameters to admittance parameters [#]_ | 
| s2t(s) | converts scattering parameters to scattering transfer parameters. | 
| z2s(z[, z0]) | convert impedance parameters to scattering parameters [#]_ |
