ENGLISH :
This code is to transform the .tro file from Visualtopo (http://vtopo.free.fr/)
into files that can be read by Therion (http://therion.speleo.sk/).
It reads .tro file and produce one .th file (file with survey data),
and one thconfig file (file that is used to compile and build the survey with Therion).
TODOS : - Correct the errors in encodings... This is the most important....
- Check all the situations possibles...
- Add title to the centerline !

Main function to convert tro to th files.
This is this function that should be called from python.
INPUTS:
fle_tro_fnme : (string) Path and name of the .tro file to convert.
if None (value by default), the function does not convert anything
but build .thconfig and config.thc files
If the path is not given, the function will look in the folder from where it is launched
fle_th_fnme : (string) Path and name of the .th file to create from the .tro file.
If None (value by default), this file is created from the .tro file name
and in the same folder than that .tro file
thlang : (string) String that set the language. 'fr' by default.
If you need english, change 'fr' to 'en' in the function definition
set 'fr' for french
set 'en' for english
... other languages are not implemented
cavename : (string) Name of the cave.
If set to None (default value), it is get from the .tro file.
icomments : (Boolean) To add (True, by default) or not (False) comments in the produced files
icoupe : (Boolean) To set (True, by default) or not (False) an extended-elevation layout in the .thconfig file
ithconfig : (Boolean) To set if the thconfig file is created (True, by default) or not
istructure : (Boolean) To set if the structure and the addditional files are created (True, by default) or not
thconfigfnme : (string) Path and name of the thconfig file.
If None (by default), path and name build from the .tro file
ithc : (Boolean) To build (True, by default) or not (False) a config file config.thc
thcpath : (string) Path to the directry that contains the config file called in the cave.thconfig file.
If used with ithc = False, this path is only used for the declaration
in the cave.thconfig
If used with ithc = True, the config file will be written in that directory.
Set to None by default
thcfnme : (string) Name of the config.thc (value by default if set to None or if ommitted)
sourcefile : (list of strings) Define the source files declared in the cave.thconfig
ex :['example.th', 'example.th2', 'example-coupe.th2']
If None or ommitted, it is build from the .tro file or the cavename
xviscale : (Real) Scale of the xvi file.
Set to 1000 by default that corresponds to 1/1000
xvigrid : (Real) Spacing of the grid for the xvi, in meters.
Set 10 by default
scale : (Real) scale of the map
Set to 500 by default that corresponds to 1/500
Errorfiles : (Boolean) If True (by default), an error will be raised if output files exists in the folder
If False, only a warning is raised, and the previous files are erased by the new ones.
Use with caution
OUTPUTS:
Depending of the parameters inputed, several files can be produced
cavename.th : survey data for Therion
cavename.thconfig : file to build the pdf's maps and others
confgi.thc : config file for the .thconfig file.
