Parameters:
_array - Array of key-value pairs to create Hash from [Array, defaults to []]
_defaultValue - Default value. Used when key doesn't exist. A key is also removed from the hash if the value is set to this default [Any, defaults to nil]
_clearOnDefault - Setting default value behaves like a remove

Returns:
Newly created Hash [Hash]
