EVERY_TCL : (thm_tactical list -> thm_tactical)
STRUCTURE
SYNOPSIS
Composes a list of theorem-tacticals.
DESCRIPTION
When given a list of theorem-tacticals and a theorem, EVERY_TCL simply composes their effects on the theorem. The effect is:
   EVERY_TCL [ttl1;...;ttln] = ttl1 THEN_TCL ... THEN_TCL ttln
In other words, if:
   ttl1 ttac th1 = ttac th2  ...  ttln ttac thn = ttac thn'
then:
   EVERY_TCL [ttl1;...;ttln] ttac th1 = ttac thn'
If the theorem-tactical list is empty, the resulting theorem-tactical behaves in the same way as ALL_THEN, the identity theorem-tactical.
FAILURE
The application to a list of theorem-tacticals never fails.
