/**
* An object for interpreting a trace according to a chosen platform
*
* <p>
* Platform selection is a bit of a work in progress, but the idea is to allow the mapper to choose
* relevant languages, compiler specifications, data organization, etc., based on the current
* debugger context. Most of these are fairly straightforward and relatively static. If the back-end
* creates the trace with an actual language (non-DATA), then there's a default mapper for "known
* hosts," (but this can be out prioritized by more complex mappers). If the back-end creates a
* trace with a DATA language (usually indicating it doesn't recognize the target architecture),
* then some pluggable examine the name of the debugger and its reported architecture to try to map
* it on the front end. There may not be any good opinions, in which case, the user can override
* with any language. That's the "simple" cases.
*
* <p>
* In more complex cases, e.g., WoW64, the mapper may need to adjust the recommended language based
* on, e.g., the current program counter and loaded modules. Essentially, it must determine the CPUs
* current ISA mode and adjust accordingly. There are currently two known situations: 1)
* Disassembly, and 2) Data (namely pointer) Organization, controlled by the Compiler Spec. The
* selection logic differs slightly between the two. For disassembly, we allow the mapper specific
* control of the selected platform, based on the starting address. For data placement, we allow the
* mapper specific control of the selected platform, based on the current PC. Note that the starting
* address of the data itself may not always be relevant. At the moment, because of limitations in
* the {@link Program} API, we actually cannot support selection based on placement address.
* Instead, at the time we ask the mapper to add a platform to the trace
* ({@link #addToTrace(TraceObject, long)}), we provide the current focus and snap, so that it can
* derive the PC or whatever other context is necessary to make its decision. The returned platform
* is immediately set as current, so that data actions heed the chosen platform.
