Scripted Workflow

1. Harmonize - Using GoogleSheet Data Key, combine all raw data files. Creates archival data in long format.

2. Wrangle P Fractions - Sum P fractions conditionally by dataset to create relevant P sums (e.g., "total", "slow", etc.)

3. Attach Ancillary Data - Join on ancillary data to the data created by step 2 for use in statistics/visualization

4. Extract Spatial Information - Grabs the resulting csv from Step 3 and add on lithology and soil order data for lat/lon coordinates

5. Statistics Prep - Subset the data made by step 3 into scientifically-relevant groups for testing particular hypotheses

6. Calculate Averages - Accept all 'stats-ready' files and average to both plot- and site-level

7A. Graphs - Make graphs/figures from the data created by step 4 and 5

7B. Statistics - Perform statistics on data (likely only data from step 4 but maybe step 5 too)
