$title Test consistent compile time error checking when loading symbols (LOAD15,SEQ=904)

$onText
This test ensures consistent error checking when loading data into GAMS with

- $[gdx]load                [CT load]
- execute_load              [ET load]
- $offEmbeddedCode
  - explicit loaded sybols  [CT expl]
  - implicit loaded sybols  [CT impl]
- endEmbeddedCode
  - explicit loaded sybols  [ET expl]
  - implicit loaded sybols  [ET impl]
  
Not everything behaves the same. This gives an overview about the test that
expect an error (ERR) or should work fine (OK). Some tests cannot be done (-).
This can be sorted in 6 categories:

                                            |CT load|ET load|CT expl|CT impl|ET expl|ET impl|
---------------------------------------------------------------------------------------------
Errors in any case
Not allowed to change protected symbols     |  ERR  |  ERR  |  ERR  |  ERR  |  ERR  |  ERR  |
Symbol loaded needs to be a "GDX Type"      |  ERR  |  ERR  |  ERR  |  ERR  |  ERR  |  ERR  |
Symbol loaded need to be of same dimension  |  ERR  |  ERR  |  ERR  |  ERR  |  ERR  |  ERR  |
Singleton with more than one entry          |  ERR  |  ERR  |  ERR  |  ERR  |  ERR  |  ERR  |
---------------------------------------------------------------------------------------------
Errors in any case - but cannot be tested for implicit loading
Symbol loaded need to be a valid identifier |  ERR  |  ERR  |  ERR  |   -   |  ERR  |   -   |
Symbol loaded need to be known              |  ERR  |  ERR  |  ERR  |   -   |  ERR  |   -   |
No suffix allowed                           |  ERR  |  ERR  |  ERR  |   -   |  ERR  |   -   |
---------------------------------------------------------------------------------------------
Errors in any case - but implicit loading
Symbol loaded cannot be an Alias            |  ERR  |  ERR  |  ERR  |   OK  |  ERR  |   OK  |
---------------------------------------------------------------------------------------------
Errors at ET, but OK at CT
Can not assign external input symbol        |   OK  |  ERR  |   OK  |   OK  |  ERR  |  ERR  |
Cannot assign to domain set                 |   OK  |  ERR  |   OK  |   OK  |  ERR  |  ERR  |
Cannot redefine loop control set            |   OK  |  ERR  |   OK  |   OK  |  ERR  |  ERR  |
---------------------------------------------------------------------------------------------
Errors at CT, but OK at ET
Cannot load symbol from implicit GDX input, |  ERR  |   OK  |  ERR  |  ERR  |   OK  |   OK  |
   if it was not declared as external input
---------------------------------------------------------------------------------------------
Special ET load treatment
Symbol loaded need to be of same type       |  ERR  |   OK  |  ERR  |  ERR  |  ERR  |  ERR  |
