Objetive

Create a class "Point3D", to represent a point in 3-D space, with coordinates X, Y and Z. It must contain the following methods:

MoveTo, which will change the coordinates in which the point is.

DistanceTo(Point3D p2), to calculate the distance to another point.

ToString, which will return a string similar to "(2,-7,0)"

And, of course, getters and setters.

The test program must create an array of 5 points, get data for them, and calculate (and display) the distance from the first point to the remaining four ones.
