Detailed Description

Performs symbol analysis and records results for subsequent phases.

The symbol table maps names of identifiers to declaration nodes. There is a global map of for function names and a local map for each function. In addition it records the set of field names used in the program. Errors are reported by raising a SemanticError exception.
