Tool Transect through polygon shapefile

Transect for lines and polygon shapefiles

The goal of this tool is to create a transect along a line through a polygon map.
Eg

|____ST1_____!_ST2_!__ST1__!_______ST#_____|

(Soil type 1 etc...)

This is done by creating a table with the ID of each line, the distance
to the starting point and the different transects:

|  line_id  |  start  |  end  |  code/field  |
| 0 | 0 | 124 | ST1 |
| 0 | 124 | 300 | ST2 |
| 0 | 300 | 1223 | ST1 |
| 0 | 1223 | 2504 | ST3 |
| 1 | 0 | 200 | ST4 |
| ... | ... | ... | ... |



The tool requires an input shape with all the line transects [Transect_Line]
and a polygon theme [Theme]. You also have to select which field you want to have in
the resulting table [Transect_Result]. This can be an ID of the polygon theme if you
want to link the tables later on, or any other field [Theme_Field].
