GSoC practice 2

[cvvergara]

important: DO NOT START THIS TASK until I finish merging the other PR and generate the documentation

The file include/pgr_types.h still has 3 structures that need to be in a separate file
One per person:

• pgr_contracted_blob; - Ankur
  • will give you an opportunity to read a little about the contraction code
• path_element_t; - Mao
• pgr_path_t; - Vid

Way to work:

• depart from develop (As always create a new branch to work on)
• "imitate" other include files.
• Create the include/c_types/struct_name.h The name of the file should correspond as the name of the struct, use lower case)
• copy from pgr_types.h the sctructure in question.
  • dont forget to add the licence
• compile locally
  • the compiler is your friend, it will complain in the file you need to modify
  • got to the file and change:

#include "include/c_types/pgr_types"

to

#include "include/c_types/struct_name.h"

until it passes.
lint the header

sh tools/scripts/code_checker.sh h

commit push and verify that works on travis & appveyor and make the PR

special task for Ankur

Please read: #119

So this one is for you: pgr_contracted_blob -> Contracted_rt

to rename a file in git:

git mv pgr_contracted_blob.h contracted_rt.h

edit the file and change pgr_contracted_blob to Contracted_rt
again, let the compiler be your friend, let it figure out where in the code you need to change code
