Frame

A Frame object holds the data which is specific to one step of a simulation. It is defined as:

type Frame
    positions::Array3D
    velocities::Array3D
    step::Integer
end

i.e. it contains information about the current step, the current positions, and possibly the current velocities. If there is no velocity information, the velocities Array3D <type-array3d> is a 0-sized array.

The Frame type have the following constructor:

Frame([natom=0])

Creates a frame with space for natoms particles.
