Package statement contains our statements.
A statement is a parsed command from the recipe-file.
A statement will be one of the fixed token-types we have defined and an array of "arguments".
For example the "Run "blah"" would become a statement with token "Run" and argument "blah".
We setup an array here, but the most arguments supported is two, for the CopyFile & CopyTemplate commands.
Statement holds a single statement to be executed.
