just making sure I can commit/push things properly

test file
First attempt at survey representation

Skeleton of the code:

Doesn't include all behavior yet (like responses, blocking, branching).
I'm not sure all the functions are actually necessary: the majority of
them could be removed and instance variables of the classes could be
directly referenced/manipulated by the user, but I thought the functions
might make it clearer/easier to the user how to create the survey (could
be wrong, i don't know). Haven't decided between repl or static creation
of survey (or both) yet.
Implemented survey component classes

Implementations and changes to the previously submitted code skeleton
for simple survey creation; added another class to generate IDs for the
different components. Still in the process of testing some of the Survey
functions, have tested most of the others.
Implemented Blocks, some of the JSONizing

Not all of it is done/tested yet, haven't finished the JSON stuff
