[Libosmscout-development] Support for MODULE statement in OST and OSS files

[Tim T. <ti...@fr...>]

Hello everbody,

due to a discussion in one of the osmin tickets I recently added a 
MODULE statement to the OST files.

This allows to split the currently monolithic files in to multiple 
smaller files. This way allow to reuse parts of the files in variants of 
import or style definitions, in effect for example allowing to think in 
"layers" or "groups".

The code was simple to add however is also simple in structure, 
currently error handling could be improved and also some more 
validations could be added (currently endless recursion for example is 
possible).
