Hi John,
The situation is as follows:
* a person installs liblouis
* then installs orca
At this point orca picks up the default tables directory.
Lets say a person wishes to test new tables, and therefore modifies
LOUIS_TABLEPATH
At this point orca continues to look at the old (default) tables directory, not
the one defined in LOUIS_TABLEPATH.
Issue 9 requests for a function to be exposed so that any program that uses
liblouis can dynamically and automaticaly pick up any changes to
the tablePath.
I imagine lou_getTablesPath as a function that takes no arguments, and returns
a string, which is the current searchPath, if multiple paths are
defined then it should be a comma seperated string of paths.
