      \DOC set_basic_rewrites
\TYPE {set_basic_rewrites : thm list -> unit}
\SYNOPSIS
Assign the set of default rewrites used by rewriting and simplification.
\DESCRIBE
The HOL Light rewriter ({REWRITE_TAC} etc.) and simplifier ({SIMP_TAC} etc.) 
have default sets of (conditional) equations and other conversions that are 
applied by default, except in the {PURE_} variants. A call to 
{extend_basic_rewrites thl} sets this to be the list of theorems {thl} (after 
processing into rewrite rules by {mk_rewrites}).
\FAILURE
Never fails.
\COMMENTS
Users will most likely want to extend the existing set by 
{extend_basic_rewrites} rather than completely change it like this.
\SEEALSO
basic_rewrites, extend_basic_convs, set_basic_convs.
