Checks if a candidate operator symbol can have one of the specified fixities, and resolve it to an oeprator with
that fixity if so. If it cannot be resolved an exception is raised.

@param  candidate The candidate operator symbol to resolve.
@param  fixities  The possible fixities to resolve the symbol to.

@return The candidate operator resolved to an actual operator.

@throws SourceCodeException If the candidate operator cannot be resolved.
