 ## Initialization
-Initialization is optional if your data files are located at one of the above mentioned directories. If not, give it with ```dataPath```.

-Furthermore we've optimized file operation for multiple calculations. You may specify with ```openFileTimeout``` a timeout in ms, for which any opened file will be kept open after last access. You may specify ```0``` to disable this feature (default is 1 second). You should not use much higher values for nodejs waits on process exit for any pending timeout before exiting.

 ## ```getElevation( location [, onError] )```
 You may specify a single location or an array of two locations (bounding box).
 
-Any location may be in the format ```[ lng, lat ]``` or ```{ lng: lng, lat: lat }``` or a function returning such values. ```lat``` and ```lng``` may be functions itselfes returning the needed values.

 **Attention:** Please note, that we chose ```[ lng, lat ]``` for arrays, because it's MongoDB's internal format for geo locations.
 
-If you specify a bounding box, ```lng``` and ```lat``` will be iterated over every value inbetween in 1/120 grad steps. The result is the mean value of all eleveations.

 The optional ```onError``` function is called whenever an error occured. It's return value wil be the result of ```getElevation```
