Replace all examples using data factorDataSetDjia5Yrs with CRSP/SPGMI data

Using the `selectCRSPandSPGMI` function with `stocksCRSP` and `factorsSPGMI`, create a similar dataset to `factorsDataSetDjia5Yrs` and replace in all examples. When done, move the legacy data set to the sandbox. Related to #25

**Running `grep -rnw factorDataSetDjia5Yrs R/*.R` in the linux terminal gives me:**
