Change some types to signed for simpler code and speed
Added format to distinguish small numbers

Print 9 digits

Delete old method for printing

Improve printing six decimal places, remove trailing 0's, fix the carry when
numbers like 0.9999999 round up and print leading zeros in the decimal

The first attempt at printing floats had precision issues where the last few
digits would often be wrong. This next approach may yield a better algorithm
for numbers less than 4.29 billion, those that fit in 32 bits.

 Generalize loop to print decimal format and exponential
 Add '+' to exponent when printing larger floats

fix cppcheck "Array index 'i' is used before limits check."

Finished fixing floating point comparisons. We have streamlined how floats and doubles are checked, but we still can't compare them for equality directly. So we're directly testing for infinite and NaN before checking diffs. Also, we've officially decided that for testing purposes NaN shall equal NaN, +Inf shall equal +Inf, and -Inf shall equal -Inf. It's what most people expect during a test.

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

 Change the parameter of UnityPrintFloat from float to double (_UD)
 The call to snprintf uses implict default promotion to a double anyway

 Delete old comments from before math.h was the default isinf() method

 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

- Added ability to surround filter strings in either type of quotes
- Added ability to filter on multiple test strings as a comma delimited list
- Added ability to filter on test_file:test_name
- Added ability to use alternate syntax for filter of -f="blah"

Updated method of testing generate_test_runner script to be a FUNCTIONAL test instead of a perfect code match. Backfilled most tests and added some coverage not previously present. Still need to test new command line args and a few cmock details.

Script verification hasn't been added yet.

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

 Remove what looks like an overflow check. 'divisor' cannot overflow
  since it is the same type as 'number' and cannot be greater.

 For easier automation and searching for a test suite failure

 This solves the warnings from -Wredundant-decls when overriding the
  OUTPUT function with a function declared in another header.
 It's better this is the non-default option, since using it requires either
  a declaration of the new function OR a preprocessor guard on declaring
  UNITY_OUTPUT_CHAR (as in unity.c here), in every file using the function.
 See Pull Request #185 for more.

 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'.

 The clang compiler warns here with -Wunreachable-code
 The enum's switch statement covers all cases, so default is unused
 Leave the break in the code as a comment, to be more clear
 The history is this default case was added in f6bb7162 - compiler warning.
 Then the break was added in c6dc96f3.

With a buffer long enough, no truncation should be neccesary to format floats.

Buffer length is user settable by defining UNITY_VERBOSE_NUMBER_MAX_LENGTH,
otherwise a sensible default is used based on desired precision.

UnityPrintFloat() overflowed with some inputs (eg. FLT_MAX)
