Class collectSlumClasses

gathers slum classes from local disk/network and online repositories

this class stores the gathered classes and search paths as global variables, so if the class is re-created, it will retain the data from a previous object. (a sort of cache)

this is very useful when using this class in clients, so a call for the class in a initialization context will store the data, and the data can be quickly retrieve later in a diferent context, even whitout the original search paths.

also, a call to _refresh method (or creating the class object using the refresh parameter = True) will refresh the class caches using the cached search paths. This way, the search paths only need to be defined in the initialization context. As the class caches are global, even the _refresh method can be called from a totally separated context.

This cache mechanism frees the client from the tedious and error prone tasks of store all this data so it can be accessed in diferent contexts. It also speeds up the whole proccess, avoiding multiple un-necessary disk/network accesses.

same as local, but for online repositories. returns data in the same format as local

returns a dictionary with all classes found in the searchpath
the dictionary is organized as:

        { 'class name' :
                {'code' : 'code for the class'}
        }
