Add Mode as Summary Statistic Option

[NatalieRobbins]

When you are calculating summary statistics on a table it would be nice to have an output for statistical mode as a one line output to know the overall most frequent value in that dataset. The Frequency tool is nice but it doesn't give just one output showing what value occurred the most based off the counts.

Today I needed to calculate mode and I was very surprised to see there is not such option. I thought the option existed when the field was integer but not. I don't understand why working with raster data you can have several tools for this statistic (majority, focal, zonal...) but not as a summary stat.
Once again, QGIS rescued me. This time with the "Statistics by categories" tool that calculates mode and some other neat stats: (Q1, Q3, IQR, unique).
