/* Encapsulation of an order
|
|
*
|
|
* This structure contains one order given by a unit. These used to be
|
|
* stored in string lists, but by storing them in order-structures,
|
|
* it is possible to use reference-counting on them, reduce string copies,
|
|
* and reduce overall memory usage by sharing strings between orders (not
|
|
* implemented yet) saving approx. 50% of all string-related memory.
