view status.cpp @ 562:dfeb5ef768da

Usually a commitment phobe but everybody has they're first time. Include mant structural changes and additional definition in line with what Christophe has asked for. Some of the schemas are more complicated than Id like - I will try to think of more elegant ways of specification.

     * initializer (both in C++ and corresponding to the "-l" or
     * "--sequencelength" command-line argument).
     *
     * The problem is that the API as currently designed provides no
     * way to pass that information in to this routine; there's no
     * input parameter; nor is there in the SOAP version of this
     * query.  However, there /is/ a way to pass that information on
     * the command-line -- though that codepath is completely
     * untested.  I can see that it might be useful to provide this
     * information, but at present it's probably completely unused, so
     * the compromise for now is to hardwire the 16.
