// define max/min/abs as inline functions (safer than macros)
// can't use references here, since I want eg. max(1.,2.) to work

template <class T> 
inline 
T 
max( T a, T b ) 
{ 
   return (a>b)?a:b;  
}

template <class T> 
inline 
T 
min( T a, T b ) 
{ 
   return (a>b)?b:a;  
}

template <class T> 
inline 
T 
abs( T a ) 
{ 
   return (a>0)?a:-a; 
}
