This commit reimplements the SummaryNode class in order not to use
the ecl::smspec_node class from LibECL. Consequently, we remove
class SummaryConfig's binding to LibECL.
Class SummaryNode maintains the same information as before. We also
implement a "named constructor" strategy to assign data members that
only make sense for a subset of the node categories. The previous
member function 'type' is renamed to 'category' to identify the
attachment category (e.g., Well, Group, Field, Block, Region). In
turn, we introduce a new 'type' member function to identify the
parameter kind (e.g, pressure, rate, cumulative total, well count)
represented by a given node. We furthermore capture whether or not
the node is a user defined quantity (i.e., a UDQ).
We reimplement the keyword classifier operations that are currently
needed as free functions named 'is_*()' in SummaryConfig.cpp.
Note that in addition to the renamed member functions of class
SummaryNode, this commit also switches the summary key strategy for
block parameters. Rather than capturing the 'ijk' values
individually as "BOSAT:3,3,6", we now store the equivalent global
(Cartesian) index (i.e., as "BOSAT:523"). Code that directly
constructs block parameter keys must be updated accordingly.
Chase the API change in the 'Summary' constructor and update unit
tests as needed.
If the region keywords from the SUMMARY section, like e.g. RPR, are
specified without explicit region numbers a summary key is added for all
region values from 1..NTFIP, irrespective of which region values are
actually present.
Some minor hygiene, not exposing some highly internal detail. The list
of keywords ALL expands to is duplicated rather than acessible via a
method, but:
1. this is highly likely never an interesting list of applications
2. it's really only useful for testing **AND** is unlikely to change
3. unclutters the header files slightly
This object turns out to be the actual configuration object, not a
mediator state to obtain a configuration. It is therefore renamed to
reflect intent and behaviour.
