new version, major breacking changes, updated docs/doc-blocks

• The use of namespace in the global functions ezFunctions.php file.
  Usage of the global functions will require the user to begin a .php file something like:

  use function ezsql\functions\where;
  // Or
  use function ezsql\functions\{
      getInstance,
      selecting,
      inserting,
  };

• Class properties that was accessible by magic methods get/set, now PSR 1 camelCase.

• update class libraries and tests to match PSR 1, but still backwards with previous way.

• Renamed select of ez_mysqli to dbSelect.

• Renamed class method and behavior of selecting to select.

• selecting, and new inserting methods, can be called without table name, only the other necessary parameters:

  • The table name with prefix, can be preset/stored with methods tableSetup(name, prefix), or setTable(name), setPrefix(append), if called without presetting, false is returned.
  • This feature will be added to all database CRUD access methods , each method name will have an ing ending added.

• Removed global functions where table name passed in, use functions as outlined above using preset table names ending with ing.
