add UNITY_OUTPUT_FLUSH to make sure we get the output we need on aborted tests and whatnot.

 Add test for failure count and UnityEnd return value
 Cover printing escape codes with length parameter
 Full statement coverage

 More statement coverage on NULL input feature

 Get test coverage on this feature for int, float, & double

 Add config flag for 64-bit, max covered lines even with 32-bit compilers
 Always print uncovered lines, delete separate make target

 These were aimed at preventing the internals header from declaring
  a prototype for 'int UNITY_OUTPUT_CHAR(int);'. The second part fixed
  an omitted declaration in the tests caused by the first commit.
 Will replace the default behavior & add an option for this in next commit

 Revert the previous commit. Add tests for extended enum cases.
 Fix crash due to accessing 'trait_names' array out of bounds.
 Adding an extra invalid value to the end of an enum causes '-Wswitch' flag
  to warn unless there is a switch default case - also enabled by '-Wall'.

 Unity is at 92% coverage now
 Run 'make -s' to see coverage information for unity.c
 Run 'make uncovered' to get missing lines output

 This fixes #168. See that github.com issue for more discussion.
 Allows the tests to build when putchar() is defined as a macro
  with parenthesis around it, as in the ARM embedded gcc compiler.

 Make core Unity rakefile helper follow Fixture define procedure.
 This commit reverts parts of 36e2ca19.

 32 or 64 bit test will fail if compiled with -m32 or -m64, repectively
  on clang or gcc
 Fixes to the failures will follow

 Now that the project is using .gitattributes, get rid of CRLF in the repo.

 Updated clang and gcc targets. Fixed spelling of LIMITS, which breaks the
  gcc_auto_sizeof.yml build.
 Commented -Wunreachable-code, Unity won't build on OSX clang with it,
  error in unity.c:769 & 932: 'default: break;' case.

 If Unity core is compiled with UNITY_OUTPUT_CHAR = putcharSpy, these tests
  will run, otherwise they are ignored and print a message
 Includes an implementation of putcharSpy, which allows checking the I/O
  from Unity during a test. Follows closely from the Fixture spy
 Tricky macros determine if putcharSpy is injected

- Fixed a big ugly error in the fancy RUN_TEST handler

We're going to use the C99 isinf() and isnan() macros wherever possible now. If your compiler doesn't support this, define UNITY_EXCLUDE_MATH_H and it will go back to the old method

the test runner generator now has the ability to also output a header file for the tests, which can get pulled into the test itself if desired.

Compares two strings until maximum n bytes (i.e. strncmp()).

Primarily -
* Added "static" to static functions.
* Added proper signature with "void" to functions without arguments.
* Marked unused arguments with "(void)".
* Removed entirely unused static functions.
* Added "const" to preserve const-correctness.
* Added function prototypes for external functions.

- Modified rakefile to look in correct directory for script unit tests
- Updated paths in script unit tests
- Updated 'expectdata' files to match latest version of generated code
- Fixed bug which prevented generate_test_runner from loading config from
yaml file.

support tests named spec as well.
clean up UnityBegin to make us not have to dig inside it to inject the filename.
Add UNITY_OUTPUT_START() and UNITY_OUTPUT_COMPLETE() for future use.

rearranged project to centralize all self-test stuff under test directory. only pull in includes when required.
