dbcsr_api – DBCSR

This is the start of a dbcsr_api, all publicly needed functions are exported here. The others remain private to the library. Currently, this is the CP2K used set. Ultimately, a reduced subset and well defined api will remain, possibly grouped in to standard and expert api. Currently, this is work in progress.
