Implement asarray for NumPy compatibilities. (#18)

* Updated .travis.yml

* Updated .travis.yml with new OS configuration

* Reduced test sizes for travis memory limits.

* Removed clover coverage from testing.

* Removed coveralls. Removed PHP 7.1 support after too many zend_heap problems.

* Allow failures for PHP 7.0 and PHP 7.1 for future investigation.

* Testing new travis.yml build

* Testing old configuration with .travis

* Updated Transformable operations and CArray to new C implementation.

* Updated travis-ci

* Test Travis

* Added logo to README.MD

* High quality README.MD logo

* Logo image reduction on README.MD

* Implemented __toString for handle CArray print_r static method. Implemented Inflatable trait to handle dynamic properties. Fixed compatibility of rows and cols dynamic properties of CArrayWrapper object.

* Implemented recently logspace CArray initializer.

* Don't use ZEND_ALLOCATION during travis build for test purposes.

* Removed CCACHE from travis file.

* Added PHP 7.2.3 to travis file.

* Implemented `asarray` for NumPy compatibilities (alias of toArray). Added asarray test to ArrayConvertTest. MemoryPointer input stdClass to CArray.
