Release v5.9

At long last support for traversing through slice, array and maps and validating at any or all levels!

see documentation for the new "dive" tag

benchmarks have slightly increased ns/op and B/ops for this functionality and an additional allocation for single field validation.

for #78

Release 5.8.1

Fix Issue with nested struct as pointer being nil causing validation to fail

Release 5.8

RGB and RGBA regexes

updated to properly validate rgb 255 or rgb percentabe, it no longer allows mixing and matching; either all percentages or all numbers from 0-155

GODOC

Added some godoc examples to better illustrate functions usages

Validators

A huge shout out to @asaskevich for having allot of these validations that I ported from his govalidator, I would not have been able to add them so quickly without his groundwork, Thanks!

ADDED:
isbn10
isbn13
uuid
uuid3
uuid4
uuid5
ascii
printascii
multibyte
datauri
latitude
longitude
ssn

Release 5.7.1

merge change forgot to call new method in test to maintain my 100% test coverage

Release 5.7

add ability to use comma and = in params i.e. excludesall=,=
added some struct caching pool to reuse objects, reduce garbage collection and reduce memory allocations.
