Detailed Description
Plasma interface.
This is an interface through which plasma data is initialized and accessed. Reading e.g. from disk is done elsewhere.
To add a new plasma instance, make sure these functions are implemented and called from this interface, and that plasma.h contains enum type for the new instance.
The interface checks which instance given data corresponds to from the "type"-field in plasma_offload_data or plasma_data that is given as an argument, and calls the relevant function for that instance.
Plasma species are referred by their index number: if a function returns e.g. an array containing species densities these are ordered as electrons first by different ion species in no particular order. However, the order is invariant and consistent across all functions.
Maximum number of plasma species is defined by MAX_SPECIES in ascot5.h.
