    Updates the database (associated with ncg) with a single measure's

    jigsaw line and sample residuals.

    Updates a database fields: liner, sampler, measureJigsawRejected,

    samplesigma, and linesigma using an ISIS control network.

    

    This function uses the pandas update function with overwrite=True. Therefore, 

    this function will overwrite NaN and non-NaN entries.



    In order to be efficient, this func creates an in-memory control network

    and then writes to the database using a string buffer and a COPY FROM call.

    

    Note: If using this func and looking at the updates table in pgadmin, it

    is necessary to refresh the pgadmin table of contents for the schema.
