usage: slf_int2d_3d.py [-h] [--force] [--verbose] [--var VAR [VAR ...]]

@brief:
Interpolate values at given points in a 2D unstructured mesh (with triangular elements)

@warnings:
* target point is outside the model => value of the nearest node is taken
* target point is exactly at a node location => node value is taken (no interpolation is required)
* target point is at the boundary of two elements => interpolation

@info:
* csv_convention for the point set:
** 3 columns (id, x, y) with colon (',') separator
** header is compulsory but order of column may vary
** id must be unique and is a string or an integer
* outCSV : CSV with columns : time, id, x, y and varID_list

  csv_filename         filename with a set of points (columns: id,x,y)
