# Function distance

Calculates:
   The eucledian distance between two points in N-dimensional spaces.
   Distance between point and a line in 2 and 3 dimensional spaces.
   Pairwise distance between a set of 2D or 3D points
NOTE:
   When substituting coefficients of a line(a, b and c), use ax + by + c = 0 instead of ax + by = c
   For parametric equation of a 3D line, x0, y0, z0, a, b, c are from: (x−x0, y−y0, z−z0) = t(a, b, c)

math.distance({pointOneX: 4, pointOneY: 5, pointOneZ: 8}, {pointTwoX: 2, pointTwoY: 7, pointTwoZ: 9})
math.distance([x1, y1, ... , N1], [x2, y2, ... , N2])
math.distance([[A], [B], [C]...])
math.distance([x1, y1], [LinePtX1, LinePtY1], [LinePtX2, LinePtY2])
