Changes from "\0x16" before, makes it easier to copy strings from output

 Works when using the putcharSpy, transparent without it

 Refactor to use the same code everywhere for FloatWithin check
 Rename and fix a few tests for new behavior, infinity == infinity

 Covers the cases where infinity == infinity

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

 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'.

 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.

 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.

 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

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

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

- rename the custom FLOAT_TRAIT type because the old name was poor

added macros for IS_DETERMINATE and IS_NOT_DETERMINATE

- rework to not bother with any of the ever-changing test frameworks in Ruby (sigh) for self-testing
- started working on cleaner floating point support. more coming.

The tests which exercise TEST_ASSERT_EQUAL_MEMORY_ARRAY use int arrays,
and hard-code the size of each element as 4 bytes. This is of course
untrue on 16-bit platforms.

Replace this hard-coded value with sizeof(int).

Previously, TEST_ASSERT_EQUAL_HEX_ARRAY was being called, and passed
arrays of type 'unsigned int'. TEST_ASSERT_EQUAL_HEX_ARRAY is an alias
for TEST_ASSERT_EQUAL_HEX32_ARRAY in *all* cases (and is documented as
such), while 'unsigned int' is 16 bits on some platforms. Unsurprisingly
this caused some tests to fail.

Fix by replacing the 'unsigned int' declarations with '_UU32'.

     - Change type of floating-point constants to single/double precision
       as appropriate.
