--Error handling
--[[ Notes:
when errors occure a new error message is concatenated to errorstring
an error message contains an error category with a sortkey
For major errors, it can also display an error message (the error message will the usually be returned and the function terminated)
More minor errors do only add a category, so that readers are not bothered with error texts

* B: invalid globe
* C: something wrong with other parameters
* D: more than one primary coord
