json patch (RFC 6902) makes it clearer in case of array contents. It is
supported by nlohmann::json and can be applied with `patch` to fill up
the json with defaults.
If a json object containing a schema is moved into the json validator it
should not be copied. At least the public interface of the validator
class schould not force the copy.
Now when json-schema-validator is installed CMake config files are installed in the lib/cmake/json-schema-validator directory.
The install json-schema-validatorTargets.cmake file properly imports the json-hpp and json-schema-validator libraries.
The install json-schema-validatorConfig.cmake file is used by CMake find_package function to include the json-schema-validatorTargets.cmake file and to set the variable JSON_SCHEMA_VALIDATOR_INCLUDE_DIRS to the install include directory.
To use find_package to find the json-schema-validator simply include.
A new test (test_cmake_install) has been added.
When NLohmann's JSON is install with CMake, it follows a certain
naming convention.
As we learned to do proper CMake-install thanks to @lkersting's work
this project now adapts to the way NLohmann is doing it. Namely:
- json-schema.hpp is now located (and installed)
in a nlohmann/-subdirectory
- the CMake library and project's name is now
nlohmann_json_schema_validator
Instead of doing non-standard acrobatics to find the json.hpp
now find_package is used in order to find NLohmann's package

This way the validator can be used static/global loading once a root-schema.
As no try/catch-compound can be placed around, it has to be a valid schema.
Related to #70
report first error message of first subschema failure for 'allOf'
make other error messages more consistent
json_validator::validate can be const
introduce error_handler 'interface'
typedefs for schema_loader and format_checker functions
remove some commented-out debugging code
