Implement aliases to mirror wordpress function naming in base Clarkson Objects #139
Description
As @SimonvdSteen noted, the method names used in CC objects differ ever so slightly from the usual WordPress equivalents. E.g. clarkson_object->get_title() instead of get_the_title. This adds to the learning curve having to guess the exact method names.
We should explore creating aliases for WordPress functions, that use the already existing logic as implementation.
