Fixed various paren matching and cond argument issues.
Fixed another paren matching problem on substring call.

Description of what we are trying to do with jointly developed my-string-contains
Problem spec brought over from Dr. Racket documentation.
Initial looking into some of the subproblems
Not a pattern per-se, but a useful thing to remember.
Another rule boolean functions and their return values in base cases
Another useful thing, also, not just scheme, you know?
Wrote a simple version of our desired function, that makes assumptions.

This soltuion only works for the cases where str1 is exactly length 1, but
it works.  So, the question is, how do we extroplate from this into something
that solves the whole problem?
Next step
Additional note about considering our smaller problem
Begin a port of our code from the smaller example problem to the main problem.

Also, create the API for match-fromb-beginning? which is a separate function
we'll write to help us.
a simple expression practice example
Wrote helper function with its own API, and copied over and modified other code from simple version
to use in our real one.
? at end thing
That code was really for match-from-beginning, not the main function.

Also, add some test cases too.
Finished writing my-string-contains? in terms of match-from-beginning?
