Package Syntax (nxm.)

Accessing Files Using the nxm. ("dot") Syntax:
- Files can also be accessed via their package name.
```
nM> plot nxm.sys.dat.world.prm
<Plots the world.prm file in the DAT area of SYS>
```
- This feature is highly recommended!
  - This is a very portable way to access files.
  - Use of this syntax is common in tests cases.
  - This is the easiest way of specifying a file in a specific option tree.

Java Experts Take Note:
This way of referring to a file is based on the Java package naming scheme. The only differences being that it must start with "`nxm.`" and it has a file extension at the end (since not all files have a .class extension). Because of this file extension, NeXtMidas enforces a strict ordering of: nxm.<option_tree>.<area>.<file_name>.<file_extension>
