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
