//==================
//define the base class for quadratic optimization classes

//@Man:
//@Memo: a base class of optimization algorithm
/*@Doc: 
  This is the base class for linear solvers included
  in COOOL. These are used to solved optimizations
  having quadratic objective function.
  Classes derived from this class inherit features of 
  QuadraticOptima. This class cannot be instantiated directly.

  QuadraticOptima currently only takes Models either double 
  or long integer. It is mostly because I tried to avoid using
  templates, due to the guliness of template features in G++. 
  Hopefully, this could be changed soon.
