/*
editedforms.c

Written by: Peter Tzannes

INPUT          ->    OUTPUT
form'i'.csv    ->    editedform'i'.txt

Compile
gcc -o <object file> editedforms.c

Run
<object file> <A number which corresponds to the number of inputs>

  The aim of this fucntion is to:
  - removes ambiguity of object coordinate system, that is, corrects all objects that 
  were measured from origin.
  - all forms have the same objecets code
  - cm and mm were correced to meters.
