WIP
Initial set-up of Travis CI
Forgot to specify source directory for cmake
Need to have dependencies installed before building
No hard tabs in YAML
Need to include all header files for stat(2)
Warning clean-up

Defining the error an info macros to false results in what are effectively
statements. On Travis, GCC gives warnings that these are statements with no
effect.
Warning clean-up

Defining the error(...) and info(...) macros to '(bool) false' on RELEASE
builds results in what are effectively statements. On Travis, GCC gives
warnings that these are statements with no effect.
Merge branch 'tests' of github.com:mattboyer/optenum into tests
Fix integer=pointer warning
Install libcheck
Added Travis CI badge to README
Install libpopt so its parser can be tested
Import int_gt from later check.h

The version of libcheck available on Travis doesn't include the
ck_assert_int_gt convenience macro present in v0.9.10. Rather than rewrite the
tests, we'll import the macros here.
Imported assert macros for pointers
Factored out check macros not present in 0.9.8
Fixed test macros for pointers
More macro fixes
Actually run some tests!

This is not a very good solution. We need a way to run all tests in one
command, the exit code of which will determine the status of the build - having
a long string of commands chained with '&&' is a poor way of implementing this.

This can likely be achieved by using CTest and 'make test'
Test logic fix
