   * This method returns the module that corresponds to the path passed as a parameter.
   *
   * @param name the name of the module we're looking for (e.g.: mod1.mod2)
   * @param dontSearchInit is used in a negative form because initially it was isLookingForRelative,
   *     but it actually defines if we should look in __init__ modules too, so, the name matches the
   *     old signature.
   *     <p>NOTE: isLookingForRelative description was: when looking for relative imports, we don't
   *     check for __init__
   * @return the module represented by this name
