* let run_test.sh create output directory
* add basic test for run_test.sh
Fix centre(...) method for regional ElementAccessor<>.
New mehods applied to read values from records an EQdata. test_20 pass quickly, but it uses just tom748_solve also in the case of constant parameters. that must be corrected.
two lines changed in sorption.cc without any result
Optimization and correction of Input::Address class
* remove old src/input/ files (why thay are resurecting over and over?)
adsorption test_20 pass for both either constant or time and space dependent parameters, this is backup commit, code will be cleaned later
Sorption::isotherms_precomputed() deleted, interpolation table creation enabled also for the case without limited solubility under consideration, limited solubility written in con-file is not obligatory any more, it is possible to let it default ("-1"), its value indicates if limited solubility is conciedered, it has been tested, temporarly I set table limits for the case without limited solubility and with constant rock matrix parameters constant, I think it should have at least maximal value from all the concentration in particular region
indication of error corrected if nr. of solubility limits do not pass nr. of adsorbing species
