// Factory to return pointer to Bertini cross-section table based on

// Author:  Michael Kelsey (SLAC)

// 20110729  M. Kelsey -- Use static instance() function to work around
//    "disappearance" bug on Linux (GCC 4.1.2).  Add diagnostics.
// 20110916  M. Kelsey -- Add "load on demand" to GetTable(), with full set
//    of channel .hh files for use with LoadTable().
// 20110923  M. Kelsey -- Add optional stream& argument to printTable(),
//    pass through.
// 20111007  M. Kelsey -- Add new gamma-n and gamma-p tables.
// 20130129  M. Kelsey -- Drop load-on-demand interfaces, fill in ctor
// 20130429  M. Kelsey -- Change instance to thread-local pointer.
// 20141121  Use G4AutoDelete to avoid end-of-thread memory leaks
