Enhancement - Plots - Flags

[leppott]

Plot data with flags.

Red dots = "F"ail

Orange dots = "S"uspect

May need to be a separate Report, e.g., Report_QC_plotflags.rmd.

Text from #118

Fail = Red triangle Suspect = Orange squar Pass = Blue circle (or whatever is current color)

discrete = black circle (same as current)

If create function for the plots easier to access in the RMD files. And opens them up to users in the console and to Shiny.
