Detailed Description

template<class T>
class semantics::Semspear_tree_parser< T >

Parses an edge of type T. The type T must have these methods: set_label(), set_word(), add_child(), and optionally set_head() to enable functionality for reading in head marker indices from the input stream. T must also have a public container of children or child pointers, accessible with a public children() method. T should have a complete_tree() method to signal that tree is built
