Class Description

 StFormulary                                                               
                                                                           
 The StFormulary class improves the TMath class by adding some often used  
 functions and calulations.                                                

 Constructor. Creates a StFormulary object.

 StFormulary destructor.

 Returns the relative diffenrence of two points.

 Calculates the x(y=0)-values of a parabola of the form
 x^2 + p * x + q = 0.

 Returns the angle between to vectors (in dim dimensions).

 Calculates the distance squared of two points in euclidian geometry.

 Calculates the distance of two points in euclidian geometry.

 Calculates the (euclidian) vector product of two vectors in three dimensions.

 Calculates the (euclidian) scalar product of two vectors

 Calculates the scalar product of the given vector with itself.

 Calculates the sum of the two n-dimensional vectors and stores the
 result in the vector P.

 Calculates the difference of the two n-dimensional vectors and stores the
 result in the vector P.

 Calculates the length of a vector in ordinary euclidian geometry.
