Implements a 1dimensional minimization along a given direction (i.e.
quadratic interpolation) It is independent of the algorithm that generates the direction vector. It brackets the 1dimensional Minimum and iterates to approach the real Minimum of the ndimensional function.

Perform a line search from position defined by the vector st along the direction step, where the length of vector step gives the expected position of Minimum.
fcn is Value of function at the starting position , gdel (if nonzero) is df/dx along step at st. Return a parabola point containing Minimum x position and y (function Value)
