Writing an Initialization Function

In the initialization function for the shared library that defines the new tag, register the tag using the function shtml_add_tag. The signature is:

NSAPI_PUBLIC int shtml_add_tag (
             const char* tag,
             ShtmlTagInstanceLoad ctor,
             ShtmlTagInstanceUnload dtor,
             ShtmlTagExecuteFunc execFn,
             ShtmlTagPageLoadFunc pageLoadFn,
             ShtmlTagPageUnLoadFunc pageUnLoadFn);

Any of these arguments can return NULL except for the tag and execFn.
