Tables by constructor

Tables of electromagnetic processes for several common constructors. To generate these tables (in reStructuredText format), call:

G4LossTableManager::Instance()->DumpHtml()

For example, use example extended/electromagnetic/TestEm0, and set the environment variables G4PhysListName to be the name of the file to write (extension .rst will be added), and G4PhysListDocDir to be the name of the directory to write the file. Set the physics list in the macro file. Also set:

/process/em/verbose 1
