func_documentation_string: Takes a namespace string and fetches that location out from
  an object/Map.  If the namespace doesn't exists it is created then
  returned.  Also allows you to set a value at that namespace (last parameter).
  @example
  // will create/fetch within `obj`: hello: { world: { how: { are: { you: { doing: {} } } } } }
  autoNamespace ('hello.world.how.are.you.doing', obj)
  
  @example
  // Will set 'hello.what.is.your.name' to 'juan'
  autoNamespace ('hello.what.is.your.name', obj, 'juan')
  
  @function module:sjl.autoNamespace
  @param ns_string {String} - The namespace you wish to fetch
  @param objToSearch {Object} - The object to search for namespace on
  @param valueToSet {Object} - Optional.  A value to set on the key (last key if key string (a.b.c.d = value)).
  @note For just checking the namespace and not creating it, use `searchObj` instead.
  @returns {Object}
