P419-017 counterex- Missing one liner with multidim array

The one liner is missing because we did not project value of array
elements in intro_projections_counterexmp. I changed the whole algorithm
of projections to allow projecting values of multidim array. Also,
moved local functions outside the main function. Added some trivial
helping functions.

* intro_projections_counterexmp
 (detect_map_types): Takes a type and return the list of successive types
  in the map and the return type. On map int (map int int) returns
  ([int; int], int).
 (last_type): Takes a list of proj_functions and returns the return type
  of the last projections_function that will be applied.
 (recreate_types): Recreates the type of the map with projected return
  type.
 (create_index_list): Returns a list of new well typed symbol for
  application in the axiom.
 (recreate_term_applications): Apply array to indices.
 (list_projection_until_base_type): Returns the list of all possible
  list of proj_functions applied to it.
 (projections_for_term): Changed the map part almost completely. We do
  not call this function recursively but we used other functions to get
  the recursive behavior.
