Methods
Override the function that constructs the result arrays to also prepare a 'php' item in the array
Set the closed blocks that the template parser should use
Set the open blocks that the template parser should use
Add a closed block callable to allow <% name %><% end_name %> syntax
Add a closed block callable to allow <% name %> syntax
Ensures that the arguments to addOpenBlock and addClosedBlock are valid
Values are bare words in templates, but strings in PHP. We rely on PHP's type conversion to back-convert strings to numbers when needed.
The basic generated PHP of LookupStep and LastLookupStep is the same, except that LookupStep calls 'obj' to get the next ViewableData in the sequence, and LastLookupStep calls different methods (XML_val, hasValue, obj) depending on the context the lookup is used in.
If we get a bare value, we don't know enough to determine exactly what php would be the translation, because we don't know if the position of use indicates a lookup or a string argument.
As mentioned in the parser comment, block handling is kept fairly generic for extensibility. The match rule builds up two important elements in the match result array: 'ArgumentCount' - how many arguments were passed in the opening tag 'Arguments' an array of the Argument match rule result arrays
This is an example of a block handler function. This one handles the loop tag.
This is an open block handler, for the <% debug %> utility tag
This is an open block handler, for the <% base_tag %> tag
This is an open block handler, for the <% current_page %> tag
The TopTemplate also includes the opening stanza to start off the template
Compiles some passed template source code into the php code that will execute as per the template source.

Argument_DollarMarkedLookup($res, $sub)
If we get a bare value, we don't know enough to determine exactly what php would be the translation, because we don't know if the position of use indicates a lookup or a string argument.
Instead, we record 'ArgumentMode' as a member of this matches results node, which can be:
- lookup if this argument was unambiguously a lookup (marked as such)
- string is this argument was unambiguously a string (marked as such, or impossible to parse as lookup)
- default if this argument needs to be handled as per 2.4
In the case of 'default', there is no php member of the results node, but instead 'lookup_php', which should be used by the parent if the context indicates a lookup, and 'string_php' which should be used if the context indicates a string

As mentioned in the parser comment, block handling is kept fairly generic for extensibility. The match rule builds up two important elements in the match result array: 'ArgumentCount' - how many arguments were passed in the opening tag 'Arguments' an array of the Argument match rule result arrays
Once a block has successfully been matched against, it will then look for the actual handler, which should be on this class (either defined or extended on) as ClosedBlock_Handler_Name(&$res), where Name is the tag name, first letter captialized (i.e Control, Loop, With, etc).
This function will be called with the match rule result array as it's first argument. It should return the php result of this block as it's return value, or throw an error if incorrect arguments were passed.
