Writing packages: definition of constant symbols, subroutines, types, and parameters

Description

Packages are libraries written in the Mosel language that extend the language with

constant symbols (myconstants.mos)
subroutines (definition of several overloaded versions of a procedure in solarraypkg.mos, generic implementation using union types and iterator in solarrayanypkg.mos)
types (definition of a structure 'arc' to represent arcs in a network with a function to access information: arcpkg.mos)
parameters (definition of real/integer/string/boolean valued package parameters: parpkg.mos)

Further explanation of this example: 'Mosel User Guide', Chapter 16 Packages
