"""
   ASTEVAL provides a numpy-aware, safe(ish) "eval" function

   Emphasis is on mathematical expressions, and so numpy ufuncs
   are used if available.  Symbols are held in the Interpreter
   symbol table 'symtable':  a simple dictionary supporting a
   simple, flat namespace.

   Expressions can be compiled into ast node for later evaluation,
   using the values in the symbol table current at evaluation time.
