16   This has parameter handling stuff which can be shared between Cbc and Clp (and Dylp etc).
17
18   This (and .cpp) should be copied so that it is the same in Cbc/Test and Clp/Test.
19   I know this is not elegant but it seems simplest.
20
21   It uses COIN_HAS_CBC for parameters wanted by CBC
22   It uses COIN_HAS_CLP for parameters wanted by CLP (or CBC using CLP)
23   It could use COIN_HAS_DYLP for parameters wanted by DYLP
24   It could use COIN_HAS_DYLP_OR_CLP for parameters wanted by DYLP or CLP etc etc

30/*! \brief Parameter codes
31
32  Parameter type ranges are allocated as follows
33  <ul>
34    <li>   1 -- 100     double parameters
35    <li> 101 -- 200     integer parameters
36    <li> 201 -- 250     string parameters
37    <li> 251 -- 300     cuts etc(string but broken out for clarity)
38    <li> 301 -- 400     `actions'
39  </ul>
40
41  `Actions' do not necessarily invoke an immediate action; it's just that they
42  don't fit neatly into the parameters array.
43
44  This coding scheme is in flux.
