* [Slim] Decouple Api files into separated PHP Classes
This enhancement required for modular testing and code coverage generating.
* [Slim] Define all app routes in SlimRouter PHP Class. Generate new samples
* delete Go client sample output dir before rebuild
* purge go-petstore-withXml samples output dir before build
* update samples
* fix go-petstore-withxml.sh echo path
* fix schema/definition name as 'file'
* update samples
* Trigger CI due to previous Shippable race condition
* add fix with toModelName(openAPIType)
* update tests for file schema/definition name
* Update 3.0 test spec
* update samples
* update samples for jaxrs-cxf
* Trigger CI due to previous Shippable race condition
* add back explode
* add file suffix fix for _test.go
* Trigger CI due to previous Shippable race condition
* Trigger CI due to previous Shippable race condition
* Trigger CI due to previous Travis CI stall
* Trigger CI due to previous Travis CI stall
* Trigger CI due to previous Shippable race condition
* add Go client test testFilenames
* Added a .gitignore to ignore the build folder
* Added a CMakeLists and a basic implementation of a double linked list
* Added the pet model
* changed the behaviour when a list gets freed - the data of each element doesn't get freed anymore
* Added the tool uncrustify in order to make code look better
* Uncrustified code
* added an implementation(constructor and deconstructor) for the category model
* Added a third party JSON library
* The pet struct now uses pointers for its members; the pet struct now has a proper constructor and a basic toJSON method
* The pet model now gets fully serialized into JSON
* Fixed the example url...
* Added third party library libcurl
* Modified category struct and added an unit test
* Added a foreach macro and added two functions
* Added a tag model and an unit test
* the pet struct now uses no double pointer for it's name anymore and no pointer for the enum status anymore; the pet struct can now be fully converted to json and parsed from json
* Added the struct APIClient and an unit test
* Uncrustified the unit test for category
* Added ifdef in pet.h to prevent errors
* Added one API endpoint to get a pet by id
* Added a "== 0" comparison that I forgot
* Added some kind of debug functionality to test-petApi.c
* Removed the DEBUG define
* Moved the c petstore example from samples/client/c to samples/client/petstore/c
* Renamed function getPetById to petApi_getPetById to avoid name collisions
* Removed unecessary method in list.c
* Added POST functionality; added petApi_addPet method and improved unit-test for petApi; cleaned up some code in apiClient
* removed two methods in list.c(string/tag to JSON) and moved their code directly in the pet_convertToJSON method
* Removed old, already commented out, puts artifact in apiClient.c
* Added a convertToJSON method to the category model
* Added a convertToJSON method to the tag model
* changed how the convertToJSON method works in the pet model
* Adjusted the unit-tests on how the convertToJSON method now works(now returns a cJSON* instead of a char*)
* apiClient_t now needs to be given to API methods as a parameter. This means apiClient_t can now be reused in multiple methods.
* Added an untested concept for how authentication could be handled
* Tested basicAuth using wireshark and added untested OAuth2 feature
* Added support for api key authentication using the http-header and tested functionality using wireshark
