Coded functionality now supports basic un-typed substitutions from the
surrounding dictionary. For example:
value 1.2345;
#codeExecute
{
scalar s = $value;
...
};
It also now supports the more functional typed substitutions, such as:
direction (1 0 0);
#codeExecute
{
vector v = $<vector>direction;
...
};
These substitutions are now possible in all code blocks. Blocks with
access to the dictionary (e.g., #codeRead) will do a lookup which will
not require re-compilation if the value is changed. Blocks without
access to the dictionary will have the value directly substituted, and
will require recompilation when the value is changed.
Specific names have been given for expand functions. Unused functions
have been removed, and functions only used locally have been removed
from the namespace. Documentation has been corrected. Default and
alternative value handling has been removed from code template
expansion.
