Thorough redesign of the LP/MIP interface (#44)

  • Redesigned class structure
  • Redesigned iterators
  • Some functions in the basic interface redesigned
  • More complete setting functions
  • Ray retrieving functions
  • Lot of improvements
  • Cplex common env
  • CLP macro definition to config.h.in
  • Update lp.h to also use soplex and clp
  • Remove default_solver_name
  • New solverName() function in solvers
  • Handle exceptions for MipCplex? test
  • Rename tolerance parameter to epsilon
  • Rename MapIt? to CoeffIt?
  • Lot of documentation improvements
  • Various bugfixes
