Method to load ascii position file.


<!-- ##### SECTION Long_Description ##### -->
<para>
Ascii format is a plain text format to store elements and their position. The first line is a commentary and is not read. Then, the next two lines must contains each three numbers, describing the box containing the data. The first number is the length on x direction. The next two numbers are on one hand the component on the same x direction and on the other hand the other component on a direction orthogonal to the x direction, setting thus the y direction. The three other numbers are the component of the z direction on first, the x direction, then the y direction and finally in a direction orthogonal both to x and y directions. After these three first lines, all other lines can be blank, beginning with a '#' character or containing three numbers and a label name for the element.

<para>The read_ascii_file() method is used to try to load an ascii file in memory. Other methods are quite private and just put here for other loader which wants to share the code of this loader (see read_xyz_file() for instance).
