The interface for a script.
All the methods that all scripts for all languages must implement. These are tiny pieces of data that can be run like miniature programs.
These can be executed by passing them to the appropriate Script Manager.
This uses multiple inheritance to minimize the amount of features a scripting langauge with need to implement. It is expected that a simple scripting language may only need to implement the base iScript interface. Other languages that support more features can have their script classes multiply inherit from the other classes like

|
pure virtual |
This adds an argument to be passed to the script.
All arguments added with this are passed in FIFO order to the Script during or just before execution. This should normally run in constant time. Some scripting implementations may change the order arguments are passed if doing it another way mays more sense.
| Arg | This accepts a CountedPtr to a script argument and The script shares responsibility with caller for deleting the argument. |
Implemented in Mezzanine::Scripting::Lua::Lua51Script.

Does this script support multiple return values.
Some scripting language support return tuples of values(Python), return an array of values (javascript), returning tables made of records which are groups of values(sql), and some allow return an arbitrary number of items that could be tables, or values and allow for tables to contain more tables and values(Lua). This allows for checking for an interface to retrieve some of these.

This should run in constant time. It still might be slower than removing and readding just one a few arguments in simple cases

If your only handle to this is a pointer of type iScript this can be called to get a pointer to an iScriptMultipleReturn if it would be valid.

Get a pointer to the most Derived type of this class.

Remove an argument based on a CountedPtr to the script.
This searches through the internal list and removes the first entry it finds matching this. This should be treated as taking linear time, relative to the total count of arguments assigned to this script, to run. This can be used with AddArgument to re-order the way parameters are passed into a script
| Arg | A CountedPtr matching the one to be removed |
Implemented in Mezzanine::Scripting::Lua::Lua51Script.

pure virtual |
Remove a Script argument based on the order it will be passed into the Script at Execution.
This removes the specified Argument from the internal list. This should be treated as taking linear time, relative to the total count of arguments assigned to this script, to run.
| ArgNumber | The number of the Argument to be removed. This behaves similar to an array or vector as it starts counting at 0. |
Implemented in Mezzanine::Scripting::Lua::Lua51Script.
|
pure virtual |
Sets the string version of the script.
| Code | A string that defines the source code to be executed or compiled whne running the script. |
It is recomended that when this is called that implentors clear any bytecode or any other compiled version of the script. This will prevent issues with mismatched version of source and bytecode.
Implemented in Mezzanine::Scripting::Lua::Lua51Script.
