Detailed Description

Read XYZ and EXTXYZ files.

Remarks

The file structure is nLine reads: ++line2 lines for nLine reads: +lineatoms.

Atom count [integer]
Comment line [string]
nLine reads: +lineentries of the form
- Symbol [string]
- Position [float, float, float]

A trajectory is a simple concatenation of multiple XYZ files.

EXTXYZ includes a more detail specification for the comment line.
