Weekly data quality checks for mart updates

[jrlegrand]

Depends on #262 and to a lesser extent #266

Problem Statement

Without manual analysis, it's hard to know what changed week to week in our data marts.

Criteria for Success

NDC Description mart

• How many new NDCs
• How many retired NDCs
• How many NDC->RXCUI mappings changed from previous week?
• How many new FDA descriptions
• How many changed FDA descriptions
• How many retired FDA descriptions
• How many new RxNorm descriptions
• How many changed RxNorm descriptions
• How many retired RxNorm descriptions

ATC to RXCUI mart

• How may new RXCUIs
• How many retired RXCUIs
• How many RXCUI->ATC4 mappings changed from previous week?
• Did anything change with ATC1-4 codes from previous week? Would expect this to only change once yearly

Additional Information

We considered adding a task to the mart DAG that saves off an old version of the file and then does a diff and creates a table with this analysis. Or something like this.
